Thanks, I tried it but I got

Which is not the way I want it.

It looks as though that's because you don't have fixed width data. " This is an example" is 19 chars, including the leading space. You told R it was 18. " This is an " is only 12 characters.

I would say you have two fixed width fields, and three varying fields, with no delimiters. If the middle one of the three always contains digits and the others don't, you can probably extract them using sub(), but you can't use any of the read.* functions to do this: your format is too strange.

structure(list(V1 = structure(c(1L, 1L, 1L, 1L), .Label = "DF", class
= "factor"),
    V2 = c(12L, 12L, 14L, 15L), V3 = structure(c(4L, 3L, 2L,
    1L), .Label = c(" This 23 This is a", " This is 12334 Thi",
    " This is an 1232 T", " This is an exampl"), class = "factor"),
    V4 = structure(c(1L, 2L, 4L, 3L), .Label = c("e 1 T", "his i",
    "n exa", "s is "), class = "factor"), V5 = structure(c(2L,
    4L, 1L, 3L), .Label = c("an ", "his", "mple", "s"), class =
"factor")), .Names = c("V1",
"V2", "V3", "V4", "V5"), class = "data.frame", row.names = c(NA,
-4L))

Any ideas?

I have a text file similar to this (separated by spaces):

x <- "DF12 This is an example 1 This
DF12 This is an 1232 This is
DF14 This is 12334 This is an
DF15 This 23 This is an example
"

and I know the field lengths of each variable (there is 5 variables in
this data set), which are:

varlength <- c(2, 2, 18, 5, 18)

How can I import this kind of data into R, using the varlength
variable as an field separator indicator?

See ?read.fwf.
