Hello,
You're insisting in as.data.frame(cbind(...)). Don't do that. Just see
the difference:
z = data.frame(x, y)
str(z)
'data.frame': 8 obs. of 2 variables:
$ x: Factor w/ 3 levels "a",&qu
y
1 a1
2 a 1.2
3 a 1.1
4 b 1.01
5 b 1.03
6 b1
7 c2
8 c3

Subject: [R] question: data.frame data conversion
Hello, I have a data.frame with repeating rows and corresponding value. For
instance, "z" will be an example of that.
x = c("a","a", "a", "b","b",&qu
#actually, this would be more compact
data.frame(split(z[,-1],z$x))

Hi,
May be:
z<-data.frame(x,y,stringsAsFactors=FA
1.2, 1.1, 1.01, 1.03, 1.0, 2.0, 3.0)
z = as.data.frame(cbind(x,y))
> z

1 a1
2 a 1.2
3 a 1.1
4 b 1.01
5 b 1.03
6 b1

8 c3

Hello,
First of all, do _not_ create a data frame with
as.data.frame(cbind(...))
Instead, use
z = data.frame(x, y)
As for your question, try the following.
library(reshape2)
fun <- function(z){
zs <- split(z, x)
n <- length(zs)
m <- nrow(zs[[1]])
zz <- cbind(
