Of course you can use file.rename() to do this. Can you explain more the changing pattern in you case?

You can do that like below:
startingDir<-"/myDirectory"
filez<-list.files(startingDir)
sapply(filez,FUN=function(eachPath){
file.rename(from=eachPath,to=sub(pattern="xxx",replacement="newTextString",eachPath))
})

Hi,
Try:
from1 <- list.files() ##folder where files are stored
?from1
#[1] "p126r62_5t19880613_nn1.tif.gz"
"p126r62_5t19880613_nn2.tif.gz"
#[3] "p200r65_5t19880613_nn1.tif.gz"
to1 <-
gsub("^p(\\d+)r(\\d+)\\_.{2}(\\d{8})\\_nn(.*)","LT5\\10\\2\\3XXXX_B\\4",from1)
?file.rename(from1,to1)
#[1] TRUE TRUE TRUE
?list.files()
#[1] "LT512606219880613XXXX_B1.tif.gz"
"LT512606219880613XXXX_B2.tif.gz"
#[3] "LT520006519880613XXXX_B1.tif.gz"

Hi guys,
Thank you for reply
Actually I have thousands of ?files and I would like to change file name, then I
can use it in my software ?
e.g The original file
? ? ? p126r62_5t19880613_nn1.tif.gz
The expected change
LT512606219880613XXXX_B1.tif.gz
The every single character in original files has some meaning
? p126r62_5t19880613_nn1.tif.gz
p(path)126(path number) r (raw)62(rownumber)_5t(name of
instrument)19880613(date)_nn1(band number).tif.gz
So I would like to replace some part
p ? ? ? = LT5
r ? ? ? ?= 0
_5t ? ?=remove
_nn ? ?=B
XXXX=add after date
I have tried file.rename() function but I was unable to apply this change to all
files.
is it possible to use file.rename function to apply for all file?
