```Hi,
Try:
vec1<- "mue#d/sjbijk at ruepvnvbnceiicrpgxkgcyl@keduhqvqi/ubudvxopddpfddgitrynzshzdcwgneyffrkpbxwilwqngrsals#geqmtkcpkp/qecgdfa#uag"

library(seqinr)
res<-lapply(0:4,function(i) lapply(2:5,function(j) splitseq(s2c(gsub("[#@/]","",vec1)),word=j,frame=i)))
#or
library(stringr)
res1<-lapply(0:4,function(i) lapply(2:5,function(j) splitseq(s2c(str_replace_all(vec1,"[[:punct:]]","")),word=j,frame=i)))
#or
res2<-lapply(0:4,function(i) lapply(2:5,function(j) splitseq(s2c(gsub("[^[:alnum:]]","",vec1)),word=j,frame=i)))
identical(res,res1)
#[1] TRUE
identical(res,res2)
#[1] TRUE
res[[1]][[1]]
# [1] "mu" "ed" "sj" "bi" "jk" "ru" "ep" "vn" "vb" "nc" "ei" "ic" "rp" "gx" "kg"

>I need to split  a vector into 2, 3, 4 and 5 letter words.  Characters like "#", "@","/" should be excluded.

>For example:
>2 letter split: "mu", "ed",...
>3 letter split: "mue","dsj",...
>4 letter split: "mued",...
>..............................
>Another split doing the same from the second letter
>2 letter split: "ue", "ds",....
>3 letter split: "ued",'...
>----------------------------
>5 letter split: "uedsj",...
>---------------------------------------------
>Continue the same process upto the fifth letter "s".
