[R] character vector -> numeric matrix ??

[Brian Koch]

If your entire dataset looks like your example, try:

do.call(rbind, sapply(zz, strsplit, split=""))

Note that strsplit() requires a character vector as its first parameter.

Dear R users... 

I'd like to change this character vector, "zz",  

zz <- c("12","56","89")

to the following numeric matrix.

     [,1] [,2]
[1,]    1    2
[2,]    5    6
[3,]    8    9


Actually, "zz" vector has a long length.

Any comments will be greatly appreciated.

Kathryn Lord
