list - Executing two commands into one command in R -


i have 12 files in directory folder, type of files csv , sas7dbat. used command upload them: 

filelist1 = list.files(path=".", pattern=".csv")  filelist2 = list.files(path=".", pattern=".sas")

i tried write command, didn't go well:

filelist = list.files(path=".", pattern= c(".csv", ".sas")

in addition, need 2 make them 1 command: 

  list2env( lapply(setnames(filelist1, make.names(paste(2008:2016, "_kvish_1_10t",   sep= ""))),        read.csv), envir = .globalenv)  list2env( lapply(setnames(filelist2, make.names(paste0(2005:2007, "_kvish_1_10t", sep= ""))),        haven::read_sas), envir = .globalenv)

pattern takes 1 argument.

if want find several elements, should try regex : 

filelist <- list.files(path=".", pattern= "\\.csv|\\.sas")

best,

colin
