First install mysql workbench here:

http://dev.mysql.com/downloads/workbench/

then install mysql server here:

http://dev.mysql.com/downloads/mysql/

And then , on mac terminal, use command:

cd /usr/local/mysql/bin
sudo ./mysqld_safe --console

xm<-data.frame(x)

object<-lm.ridge(X1~.,xm,lambda=0.003)
coef4.1<-coef(object)
acoef<-abs(coef4.1)
for (i in 2:6)
{xstar[,i]<-x[,i]/acoef[i]
}

An algorithm that can normalize the columns and rows of a matrix:

m<-matrix(c(1,3,5,4,7,4,6,1,5),3,3)
rowsum<-c(1,2,3)
colsum<-c(1,2,3)
while((max(rowsum)-min(rowsum))>0.0001 && (max(colsum)-min(colsum))>0.0001)
{ for (i in 1:3)
{
rowsum<-apply(m,1,sum)
m[i,]<-m[i,]*12/rowsum[i]
}
for (i in 1:3)
{
colsum<-apply(m,2,sum)
m[,i]<-m[,i]*12/colsum[i]
}
}

To get the source codes from R

In a package: use methods(package)
In a function: input the name of the function, then return, if the function is in some where, then getAnywhere(function)


fun1<-function(n)
{ if(n==1)
  list(success="The computation is successful!")
else
if (n<=0)
list(fail="We need a positive number!")
else while(n!=1)
{
if (n%%2==0) n<-(n/2)
   else n<-(n*3+1)
print(n)
}
}

fun1(3)

How to export a data frame from R into SAS

Using the package “foreign”, and the function “write.foreign”
Suppose we have a data frame named “b” in R. If the data is not data frame, we can use “as.data.frame” to convert it into a data frame. We set up an empty file name a.txt, then we write a sas code to infile the data from a.txt. At last, we use the following codes to finish the export.

library(foreign)
a<-matrix(c(1,2,3,4,5,6,7,8,9),nrow=3)
b<-as.data.frame(a)
write.foreign(b,"C:\\Users\\Soemone\\Desktop\\a.txt","C:\\Users\\Soemone\\Desktop\\a.sas",package="SAS",dataname="one")

dataname is an optional statement, using that we can convert the name of the data in SAS into the one that we want such as “one” here. May try different kind of data file such as Excel file?

In fact, we do not need to set up the data file a.txt and the sas file a.sas. Just write a path for the data file and the sas codes file, but do not need to put anything there. Then run the codes above, it works.

R can not read Excel file xls directly unless the excel file is converted into the csv file.

Draw multiple graphs in graph.

R codes:

par(mfrow=c(2,2))
a=matrix(rep(0,16),nrow=4)
for (i in 1:4)
{plot(rnorm(a[i,]))
}

Results:


Another codes:
par(mfrow=c(2,3))
a=matrix(rep(0,24),nrow=6)
for (i in 1:6)
{plot(rnorm(a[i,]))
}









par(mfrow=c(3,2))
a=matrix(rep(0,24),nrow=6)
for (i in 1:6)
{plot(rnorm(a[i,]))
}










par(mfcol=c(2,3))
a=matrix(rep(0,24),nrow=6)
for (i in 1:6)
{plot(rnorm(a[i,]))
}










par(mfcol=c(3,2))
a=matrix(rep(0,24),nrow=6)
for (i in 1:6)
{plot(rnorm(a[i,]))
}










Outer:
x<-c(1,1,1,1,1)
y<-c(1,1,1,1,1)
pf<-function(x,y){x+y}
z<-outer(x,y,FUN="pf")

How to find the rank of a matrix?
qr()$rank
example:

 (a<-diag(c(1,1,1)))
     [,1] [,2] [,3]
[1,]    1    0    0
[2,]    0    1    0
[3,]    0    0    1
qr(a)$rank
[1] 3

If you wish to know the index positions of TRUE elements of a logical vector x, then use which(x).
example:
x<-c(1,1,1,2,3,3,3,4,4,4)
which(x%%2==0)
4  8  9 10

 x<-c(1,1,1,2,3,3,3,4,4,4)
 a=which(x%%2==0)
 (x[a])

How to use sink function in R:

Example:

sink("R001.txt")
x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1)
A <- matrix(x, ncol=3)
A
A.prima <- t(A)
A.prima
dim(A)
dim(A.prima)
sink()

Metropolis sampler:

1. Start with some initial value
2. Given this initial value, draw a candidate value  from some proposal distribution.
3. Compute the ratio  of the density at the candidate and initial points, .
4. With probability min(, accept the candidate point, else retain the current point.
5. Return to step 2.

Using R to do a  Metropolis sampler:

R codes:

sig1=0.5
sig2=0.1
sig3=10
n=500
x1=rep(0,n)
x2=x1
x3=x1
x1[1]=-10
x2[1]=0
x3[1]=0
for(i in 2:n)
{y=rnorm(1,0,1)*sig1+x1[i-1]
u=runif(1,0,1)
alpha=dnorm(y,0,1)/dnorm(x1[i-1],0,1)
if (u<=alpha)
{x1[i]=y}
else
x1[i]=x1[i-1]
}

plot(x1,type="l")

Metropolis-Hastings sampler:

1. Start with some initial value
2. Given this initial value, draw a candidate value  from some proposal distribution.
3. Let  denote the probability of  given the current value is . Compute the ratio  of the density at the candidate and initial points, .
4. With probability min(, accept the candidate point, else retain the current point.
5. Return to step 2.




R codes which generated a Metropolis-Hastings sampler for a scaled inverse Chi- square distribution:

The MCMC codes deal with generating a Metropolis-Hastings sampler for a scaled inverse Chi-square distribution.

Recall that we can write the probability distribution for a scaled inverse Chi-square as:
Where n is the degrees of freedom, a is the scaling parameter. Here we will assume n=5,a=4. First, we need to define a function f(x,n,a)  in R:

f<-function(x,n,a) x^(-n/2)*exp(-a/(2*x))

First we need to specify a vector for the chain. Let’s call it met and give it length 5000.

met<-numeric(5000)

Lets now start the chain, say at value 1. We will call the current value in the chain last,

last<-1

We use a normal Chi-square distribution with 5 degrees of freedom. Then the codes will be:

for( i in 1:5000)

{ cand<-rchisq(1,5)
  alpha<-(f(cand,5,4)/f(last,5,4))*(dchisq(cand,5)/dchisq(last,5))
if  (runif(1)<min(alpha,1))
last<-cand
met[i]<-last}
plot(met,type=”l”)

























Plot a histogram, and control the width of the columns using “lwd”.

a<-c(0,0,1,0,0,1.5,0,0,0,1.3,0,0,2.1)

plot(a,lwd=2,type="h")



















a<-c(0,0,1,0,0,1.5,0,0,0,1.3,0,0,2.1)

plot(a,lwd=5,type="h")

Using R codes to write the logistic simulation:


beta<-read.table("C:\\Users\\Soemone\\Desktop\\Guelph\\WinBugs\\bino\\map1.csv",sep=",",header=TRUE)
bet<-beta$effect

n<-numeric(nrow(x))
r<-numeric(nrow(x))
p<-numeric(nrow(x))

for (i in 1:nrow(x))
{n[i]=rpois(1,32)
p[i]=x[i,]%*%bet
p[i]=exp(p[i])/(1+exp(p[i]))
r[i]=rbinom(1,n[i],p[i])
}

out<-matrix(c(n,r),ncol=2)

out

write(t(out),file="\\Users\\Soemone\\Desktop\\Guelph\\WinBugs\\bino\\simulationphe.csv",sep=",",ncolumns=2)


“write” can also output character strings.

a<-c(1,2,3,2,3,4,5)
