[R] size limit of string/parse a string and convert to vector

[jim holtman]

try this:

> x <- "|1,ab,2.34|2,cd,3.44|"
> # split by the "|" and remove vectors of zero characters
> x.sp <- strsplit(x, '|', fixed = TRUE)[[1]]
> x.sp <- x.sp[nchar(x.sp) > 0]
> # now split by comma
> x.comma <- strsplit(x.sp, ',')
> # you can now access you data
> x.comma
[[1]]
[1] "1"    "ab"   "2.34"

[[2]]
[1] "2"    "cd"   "3.44"
