In addition to the reshape solution posted one could use melt from
the reshape package:
melt(df1, id = 1:2)

Hello Experts,
how do I reformat a data frame in the way described below:
df1:
IDdesc resist thick temp

For heaven's sake, please stop sending repeat emails and send your R code
that can reproduce the error.

I'd like to compare tests based on the mixed model representation of additive
models, testing among others
y=f(x1)+f(x2) vs y=f(x1)+f(x2)+f(x1,x2)
(testing for additivity)
In mixed model representation, where X represents the unpenalized part of the
spline functions and Z the wiggly parts,
You want to reshape from wide into long format: see help(reshape).
For your example this should look something like
df2 - reshape(df1, varying=list(c(resist,thick,temp)), direction=long,
v.names=c(Value), timevar=Param,
idvar=ID,
Hi all!
I do hope question from newcomers are wellcome here! Thanks in advance.
Trying to catch up and to acquired the needed background to easily
read R documents it is being a bit hard to me to get into the
required concepts to deal with data.

Hi all.
I need some help computing multidimensional pvalues of a multivariate data
set.
chisq.test(x[,1],x[,2])$p.value
i need a command or loop that creates me a vector or a matrix (each variabe
with each variable) would be even better for the p.values of the variables
of a data set.

Dear list members,
I have to combine dataframes together. However they contain different
numbers of variables. It is possible that all the variables in the
dataframe with fewer variables are contained in the dataframe with
more variables, though it is not always the case.

Hi all.
i am desperating. i need a matrix of p.values from an chi square test. i
had it already work but than my computer collapsed when taking the whole
data set 800x260 into account. i am sure it looked like this but it doesn't
work now. can anybody help me? thanks in advance.
Or, try this:

It's interesting to compare your implementation:
rbind.all - function(...) {
x - list(...)
cn - unique(unlist(lapply(x, colnames)))
for(i in seq(along = x)) {
if(any(m - !cn %in% colnames(x[[i]]))) {
how to realize the following SQL command in R?
select distinct A, B, count(C)
from TABLE
group by A, B

quit;

Thanks you very much Hadley, Stephen, and Sundar, your suggestions
all solve my problem, even if the narrower dataframe contains
variables that are new to the wider dataframe.
I'm sure glad I took the time to write instead of pursuing with my
ugly and time-consuming solution.
