All,
I have the following files in a directory and I would like only a list of those starting with ?lld" and ending with ?dat?. I used the following and it gives me the lld files
list.files(path = readpath, pattern = "^lld[A-Z0-9]")
to get just .dat files I tried
list.files(path = readpath, pattern = "^lld[A-Z0-9].dat$?) but nothing is returned
below is a dput from the first command. $ is an end of line anchor correct? What am I doing wrong?
Best,
Glenn
c("lld022017_AB7755_AS0038.dat", "lld022017_AS0039_AS5210.dat",
"lld022017_AS5211_AS7917.dat", "lld022017_AS7918_AT8661.dat",
"lld022017_AT8662_AW6667.dat", "lld022017_AW6668_AZ3066.dat",
"lld022017_AZ3067_BC9534.dat", "lld022017_BC9535_MA2230.dat",
"lld022017_MA2231_MB0288.dat", "lld022017.zip")
list.files(pattern="^lld.*\\.dat$") seems to work for me. cheers, Rolf
