[R] Help in splitting the records

[arun]

Hi,

Just a modification:
 x1<-gsub("[$]"," ",x)
read.table(text=x1,sep="",header=FALSE,stringsAsFactors=FALSE)
  #   V1   V2   V3
#1  qwer   12 qwre
#2 ewrtr 7789 ewwe
A.K.

Another approach is to use gsub() followed by read.table():

> x <- c("qwer$$12$$qwre", "ewrtr$7789$ewwe")
> x <- gsub("\\$+", "\\$", x)
> x <- read.table(text=x, sep="$", stringsAsFactors=FALSE)
> x
     V1   V2   V3
1  qwer   12 qwre
2 ewrtr 7789 ewwe
