Hi Santosh,
you may also try
require(stringr)
x <- "abcdefghijklcd"
str_locate_all(x,"cd")

But it doesn't give me desired result
Also I was trying to use the function getHTMLFormDescription from the

Hi Pele,
I think this should work

Hi Patrick,
Well tobit regression is applicable when there is censoring in the data.
Tobit regression in R has been implemented in the R package survival
An easy user interface is there in the packages AER and Zelig.

Hi folks,
I am confused whether the following is a bug or it is fine
Here is the explanation
a <- zoo(c(NA,1:9),1:10)
Now If I do
rollapply(a,FUN=mean,width=3,align="right")
I get
> rollapply(a,FUN=mean,width=3,align="right")
3 4 5 6 7 8 9 10
NA NA NA NA NA NA NA NA
But I shouldn't be
Hi ,
you can try using cov2cor(vcov(lm(calorie~height))) to get the correlation
matrix of estimated coefficients

Hope this helps
a <- matrix(runif(150),nrow=3,ncol=50)
p2r <- function(x) 100 * diff(log(x))
t(apply(a,1,function(x){p2r(c(x))}))

To install this package, start R and enter:
source("http://bioconductor.org/biocLite.R";)
biocLite("globaltest")
Hope that helps

Suman take a look if this suffices your purpous
x <- data.frame(y=as.factor(sample(0:2,1000,replace=TRUE)),x=runif(1000))
x1 <- x[x$y==0,]
x2 <- x[x$y==1,]
x3 <- x[x$y==2,]

Suppose you want to remove the 1st and the 3rd column this will do
airquality[,-c(1,3)]

try

gene, deltact))
Do ?"&" to understand the difference between & and && .

Well you can try
for(i in 1:20) {
assign(paste("ddat",i,sep="_"),data)
other processing...
}

Hey guys,
I have a doubt here , It is something simple I guess, what am I missing out
here ??
f <- function(y) function() y
tmp <- vector("list", 5)
for (i in 1:5) tmp[[i]] <- f(i)
tmp[[1]]() # returns 5;
z <- f(6)
tmp[[1]]() # still returns 5; it should return 6 "ideally" right ???
Even if I

SSH is working fine as I have checked system("ssh -l me 'ip to another

Works fine and I am getting the list of files on the other computer on my

Will it take account of the heteroskedasticity and serial correlation(

Dear R users,
I have a question here
library(AER)
library(plm)
library(sandwich)
## take the following data
data("Gasoline", package="plm")
Gasoline$f.year=as.factor(Gasoline$year)
Now I run the following regression
rhs <- "-1 + f.year + lincomep+lrpmg+lcarpcap"
m1<- lm(as.formula(paste("lgaspca
why don't you try this tmp=list(X=x,Y=y) and then lapply(tmp,fun(..))

You have to use R CMD REMOVE "Package NAME" to uninstall the package(from
Command line) .
Then R CMD build brainwaver.tar.gz
the R CMD INSTALL brainwaver.tar.gz to re install then the changes you made
you be effective
