Hi,
If you can formulate your question it in terms of actual problem you have with data.frame it would be easier to answer.
for the time being check subset() if it is what you want.

I remember having similar problem with inprod function. As far as I could

This would be a considerable extension because then the selector would

Many thanks for your kind responses.
That's a simple change and will make transform.data.frame behave more
consistently with cbind.data.frame and data.frame.
Related to above, I find rather inconsistent following behavior:

data.frame(aq, list(a=1,b=

Dear useRs,
Here is a weird behavior of transform function:
mtcars1<-matcars
transform(mtcars1,t1=3,t2=4)
Error in data.frame(`_data`, e[!matched]) :
arguments imply differing number of rows: 32, 1
instead, this works:
mtcars1$t1<-0
transform(mtcars1,t1=3,t2=4)
also works if applied
Hello Everyone,
May be a silly question.
How to pass programmatically variables which are not known in advance and
are quoted? Variables are quoted implicitly in functions like "subset"
and "transform" and explicitly in ggplot and plyr.
For instance I would like to have something like this

For various reasons I need to plot multiple ggplots on one device
