[R] Fwd: help to slip a file name using "strsplit" function

[Ivan Calandra]

Hi Gianni,

Your first example works fine, though you have unnecessary stuff in it:
strsplit("Myfile_MyArea1_sample1.txt", "_")
[[1]]
[1] "Myfile"      "MyArea1"     "sample1.txt"

The second example doesn't work because of two things: the period is a 
special character, and the fixed argument should be false:
strsplit("Myfile_MyArea1_sample1.txt", "\\.")
[[1]]
[1] "Myfile_MyArea1_sample1" "txt"

HTH,
Ivan

Dear Researchers,

I have several files as this example: Myfile_MyArea1_sample1.txt

i wish to split in "Myfile", "MyArea1", "sample1", and "txt", becasue i
need to use "sample1" label. I try to use "strsplit" but I am able just to
split as "Myfile_MyArea1_sample1" and "txt" OR "Myfile", "MyArea1",
"sample1.txt" using


strsplit(as.character("Myfile_MyArea1_sample1.txt"), ".", fixed = TRUE)
strsplit(as.character("Myfile_MyArea1_sample1.txt"), "_", fixed = TRUE)

Thanks in advance

Gianni
