Not sure what 'x2' is that you are plotting; it is not defined.
read.delimand subset return dataframes, so you don't need
data.frame.

Here is something that does work:

> x <- "shirt,size,40
+ shirt,color,10
+ shirt,length,10
+ shirt,brand, 1
+ shoes,style,5
+ shoes,brand,4
+ shoes,color,1"
> x <- read.csv(textConnection(x), header=FALSE)
>
>
> x
     V1     V2 V3
1 shirt   size 40
2 shirt  color 10
3 shirt length 10
4 shirt  brand  1
5 shoes  style  5
6 shoes  brand  4
7 shoes  color  1
> plot(subset(x, V1=="shirt")[,2:3])
