Re: [R] Importing many files from a single code
Dear Ram Kumar Basent:
I suggest you restore you file is list. I give my example that I read 50
image by 50 folder.
imgA<-list() <-create an empty list
for(i in 1:50) <-how many file you need to looping.
{
imgA[[i]]<-read.jpeg(paste("c:/DataCentre/DataPisA/A",i,"FP3.jpg",sep="")))
}
This is my example how I read 50 image in 50 folders. Hope this will hepl
you.
Best Wishes
Chuan

Re: [R] Importing many files from a single code
Exactly what do you mean by "import"? What commands are you using?
You can get a list of the files in a directory and then iterate
through reading each one in. If you use 'lapply', you can
'read.table' in some data frames and then 'rbind' them into a single
data frame. You need to be more specific on the problem you are
trying to solve.
Hey,
I am new to using R and I have a similar problem.. I have 50data sets saved
and need to write a function to combine 2 data sets out of the 50.
combine.data<-function(data1,data2){
for(data1 in (0:50))
for(data2 in (0:50))
rbind(read.table("tree.data1.dat"),read.table("tree.data2.dat"))
}
Could you please help me.. :)
Thanks heaps!

Dear R users,
Does somebody know the way to import many files by a single command

files repeatedly (one by one). If there is a way to import all files
at a time, it makes much more easy and save times too.
Thanks in advance.
