How to get mode (the most frequent value in distribution)?
Hello!
I have a continous distribution and would like to get mode (the most
frequent value in distribution). I easily found mean, median and other
basic thing but not mode function. Can anyone help?
I know there my might be problems with multiple modes, but still I think
that there should be a mode function in R.
Please send mail to R-help list and me, so I can get response faster.
Thank

Re: [Rd] corrupt data frame: columns will be truncated or padded with NAs in: format.data.frame(x, digits = digits)
James, thanks for the response.
I understand now my puzzle.
tmp <- data.frame(y1=1:4, f1=factor(c("A", "B", "C", "D")))
tmp$y2 <- NA
tmp[1:2, "y2"] <- 2
Does the job. I see that I should add a full column. In my case adding full
column of NAs and then adding values, solves my problems.
Thanks to all.

Re: Cross-building R packages
Jun hi again!
Sorry for bothering. Although I had no problem with building Windows
package under Linux, I noticed that man pages are not processed as they
should or maybe I have a problem with my setup.
My package is called 'GeneticsPed'. Instead of HTML or text files I just
got a GeneticsPed.Rd.gz in man directory of a package (this is within
GeneticsPed_0.1.zip file!). The file

F90
Hello!
Has anyone successfully compiled F90 sources in R-package? I found the
same question on r-devel list from 2002 and I wonder if there is any
progress. I heard that g95 and gfortran can be usable.
And one more thing. I have a program written in F90 and lets suppose that
compiler is not a problem. I've read manual 'Writing R Extensions' and
successfully loaded one F77 subroutine

First of all I must appologize if this has been raised previously, but

be sent to R-help.

How long is winepath available?
Hello!
Can someone provide me an estimate or relevant source of information on
how long is command winepath available or from wich version of wine? I
would need this as I work on some R[1] package R2WinBUGS[2] that calls
a Windows program WinBUGS[3] and that program needs windows paths.
Currently winepath or parsing of .wine/config is used and I wonder if I
can remove fiddling with .wine/.config.

Constrain coefs. in linear model to sum to 0
Hello!
I would like to use constrain to sum coeficients of a factor to 0 instead
of classical corner contraint i.e. I would like to fit a model like

and say get parameters

where effectA_1 represents deviation of level A_1 from intercept and

Option for "Delete downloaded files (y/N)?" in install.packages()
Hello!
I have a wish/proposal.
Is it possible to include some option in install.packages() for
Delete downloaded files (y/N)? at the end of that process. It can
be quite anoying if you must install several packages and wait
meanwhile to type y/n for each package separately.

This is not a severe bug, but an inconsistency in update.packages(). I

I would like to do something like this. In SAS I can write

hist and truehist
Hello!
Up to now I have been using hist() to display the distributions.
Howevere, I noteiced strange numbers on y (vertical) axis, if I used
probability = T or freq = F option. I thought it is a bug and launched
the R-bug system and found some posts on that matter. Brian Ripley
responded to one, that one should look at truehist() for that. Ok I can
use truehist() if I want to see the ratios
