sequencially merge multiple files in a folder
Dear all,
If the question is too easy, please forgive me since I am only few weeks old in R.
I have worked on this question a few days and still cannot figure it out.
Here I have a folder with more than 50 tab-delimited files. Each file has a few hundreds of thousands rows/subjects, and the number of columns/variables of each file varies.The 1st row consists of all the variable names.

newbie graphics question: Two density plots in same frame ?
I swear I've scoured the help files and several texts before posting
what feels like a dumb newbie question.
How can I draw two kernel density plots in the same frame ? I have
similar variables in two separate data frames, and I would like to show
their two histograms/densities in a single picture. Same units, scale,
range for both, so I'm simply trying to draw one and then add the

Missing data and LME models and diagnostic plots
Hello
Running R2.9.2 on Windows XP
I am puzzled by the performance of LME in situations where there are missing data. As I understand it, one of the strengths of this sort of model is how well it deals with missing data, yet lme requires nonmissing data.
Thus,
m1.mod1 <- lme(fixed = math_1 ~ I(year-2007.5)*TFC_,
data = long,

hypothesis testing in models
Dear all,
Being an economics student, I am trying to put together a little
tutorial/FAQ/... for those who have (more) background in econometrics rather
than in statistics -- just as I have. I'v been looking for a hypothesis
testing tool in R (just linear or also nonlinear) for model parameters, but
could not find anything so far. I did find a similar but unanswered question

function in order to plot the same graph to postscript and pdf
Hi,
I've written a function in order to plot the same graph in a postcript and in
a pdf file. Unfortunately, the second graph is always empty, i.e.:
plot.both <- function{myplot, filename}{
pdf(file=paste(filename, ".pdf", sep=""))
myplot
dev.off()
postscript(file=paste(filename, ".eps", sep=""))

biplot package
Dears,
I've been learning biplot (Gabriel, 1971) and I found the function 'biplot', inside of the package 'stats',
useful but, a bit limited.
So, I'm thinking to start a colaborative package to enhance this methods to other multivariate methods. In this
way, I would like to start it, making public a new function (biplot.pca, still in development, but running)

Modifying a built-in R function
Hello,
Something incredible (at least for me) has happen. Yesterday night I
downloaded biplot.R to edit this function and add new features I wished.
Namely I wanted to plot points belonging to different groups using different
colors and symbols. I identified which part of the original code I had to
modify. Then, I rename biplot by biplotes and executing biplotes(x), being x

help with formula and data= argument
Sorry for posting this twice, but I still have not solved this problem
and am hoping for some assistance.
I am attempting to write a function that is flexible enough to respond
to the user providing a formula (with a data= argument) or not (similar
to plot(x,y) versus plot(y~x,data=data)). I have found a method to work
with this in a simple case but am having trouble determining how to

"biplot" graphical options?
Dear R-help fellows
good afternoon.
I am struggling in the attempt to impose some graphical conditions (changing point symbols, colors, etc) to biplot function (I am using it to visualize the results of princomp) but I can't apparently manage to change anything but the axis... and I have been browsing manuals and vignettes without finding any explicit suggestions on how to operate...

Reading biplot function's source code
Hi everybody,
Excuse me for this silly question, but after searching the
help archives I'm still unable to find my way to read the
source code of the "biplot" function in R.
I have installed the mvbutils package, and tried:

which only gives me:

with no further details....

biplot breakdown help
Hi,
I am trying to understand how the biplot.prcomp is constructed so I can
manipulate it to emphasise particular observations and reduce the number of
variables shown.
The prcomp model I have ran has cor=TRUE and scale=TRUE
I have worked out from looking at str(prcomp.model) that...
prcomp.model$x = the observations ploted in the biplot
prcomp.model$rotation = the variables that form the
