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
