I assume that I have missed something fundamental and that it is there in front
of me in "An Introduction to R", but I need someone to point me in the right
direction.
> x1 <- "1159 1129 1124 -5 -0.44 -1.52"
> x2 <- c("1159","1129","1124","-5","-0.44","-1.52")
> x3 <- unlist(strsplit(x1," "))
>
>
> str(x2)
chr [1:6] "1159" "1129" "1124" "-5" "-0.44" "-1.52"
> str(x3)
chr [1:6] "1159" "1129" "1124" "-5" "-0.44" "-1.52"
>
> as.numeric(x2)
[1] 1159.00 1129.00 1124.00 -5.00 -0.44 -1.52
> as.numeric(x3)
[1] 1159 1129 1124 NA NA NA
Warning message:
NAs introduced by coercion
What do I have to do to get x3 to be the same as x2.
