Hi, my data frame is

x<-data.frame(ID=c("abc/def","abc/def/ghi","abc","mno/pqr/st/ab"))

I want to split my column ID using "/" as the place to split. How can I
do that without telling the code how many sub-columns. I could use
nchar(gsub("[^/]","",x$ID)) to get how many "/" are in each row of the
column, but could not use it to split ID in.

Thanks
