Subscripting
Dataframe1 contains a list of specific dates. Dataframe2 contains a large
dataset, one element of which is Date. How do I create a subset of
Dataframe2 that excludes the dates from Dataframe1? I know how to do it with
a left outer join vs null in SQL, but I can't figure out how to do it more
directly via the subcripts that already exist?

[Resolved] combine the data frames into comma separated list.
Hi
Thanks Gabor for your suggestion. I am posting the code that worked for me.
dataframe1 = data.frame(cbind(Src = c(1,1,1,2,3), Target1 =
c('aaa','bbb','ccc','aaa','ddd'))); #must be data frame
dataframe2 = data.frame(cbind(Src = c(2,3,4,4,4), Target2 =

Arrays of Trellis plots
hello,
the example below does not work. (i know it's not supposed, but it makes it
clear what i'm trying to achieve)
par(mfrow=c(2,1))
xyplot(y~x2|x1,data=dataframe1,pch=20)
xyplot(y~x2|x1,data=dataframe2,pch=20)
i know i could probably merge the two datasets and do something like
xyplot(y~x2|x1+dataset,data=merged)
any other suggestion?
thanks.

data.frame package?
Is there a library that is able for example to
1. merge 2 dataframes by row eg.: rbind(dataframe1, dataframe2):data.frame
2. delete a column from a dataframe del(dataframe, colname) or
del(dataframe, colindex= 1):data.frame?
3. Select lines from a dataframe by a specific function ?
select(dataframe, func=small(x){x<1}, colindex=3): data.frame?
4. converting all double columns of a data.frame

Predicting ordinal outcomes using lrm{Design}
Dear List,
I have two questions about how to do predictions using lrm, specifically
how to predict the ordinal response for each observation *individually*.
I'm very new to cumulative odds models, so my apologies if my questions are
too basic.
I have a dataset with 4000 observations. Each observation consists of
an ordinal outcome y (i.e., rating of a stimulus with four possible
