remove multiple sequenced files in R -

i created multiple files named 1:100 + random letter file:

for (i in 1:100){   file.create( paste0(i , ".txt"), showwarnings=true)    # assign random letter files   az <- sample(letters,1)   cat(az,file = paste0(i,".txt"),append=true)    #rename files, , create new file append of letters   name <- scan(file=paste0(i,".txt"), what="character")   file.rename(paste0(i,".txt"), paste0(i, name,".txt")) 

now, have lot of files named "1t, 2c, 3y,..., 100a" , want remove these files (not removing rest has in directory) file.remove function, how should remove them without naming 1 one? , directory named "exercicio03" inside?

ps.: have tried

     file.remove(paste0(i,name,".txt")) 

but removing last file "100a"

since used sample function, think can 100% sure remove these files , no others, if (did) save values became sample function. first part should have been:

 az<-na  (i in 1:100){  file.create( paste0(i , ".txt"), showwarnings=true)  # assign random letter files   az[i] <- sample(letters,1)  cat(az[i],file = paste0(i,".txt"),append=true)  #rename files, , create new file append of letters  name <- scan(file=paste0(i,".txt"), what="character") file.rename(paste0(i,".txt"), paste0(i, name,".txt")) } 

that way can afterwards remove them via :

 (i in 1:100){   file.remove(paste0(i,az[i],".txt"))  }
