There are some .fcs files in a data.000X format (where X = 1, 2, 3...) in a directory. I want to rename every n file to the following format: exp.fcs (where exp is a text from a vector) if the file to be renamed is an .fcs file.
 in other words:
I want to rename files to exp.txt, where exp is a text and not a consecutive letter(s) i.e. F, cA, K, etc.
For example, from:
data.0001, data.0002, data.0003, data.0004, data.0005, data.0006...
to
textF_a.fcs, textF_b.fcs, textF_c.fcs, textVv_a.fcs, textVv_b.fcs, textVv_c.fcs ...

I tried to do it with file.rename(from, to) but failed as the arguments have different lengths (and I don't know what it means...):

a <- list.files(path = ".", pattern = "data.*$") b <- paste("data", 1:1180, ".fcs", sep = "") file.rename(a, b)
