Matplot does not work with x being POSIXt class (PR#9412)
Hi,
Matplot works with x being Date class but not POSIXt. Here is the
example with R version 2.5.0 Under development (unstable) (2006-12-06
r40129)
Example:
x <- Sys.Date() - c(1:10)
y <- cbind(1:10, 10:1)
class(x)
## [1] "Date"
matplot(x, y)
x <- strptime(as.character(x), format="%Y-%m-%d")
## [1] "POSIXt" "POSIXlt"
matplot(x, y)

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

Bug in format.default(): na.encode does not have any effect for (PR#12318)
Hi!
If I use format() on numeric vector, na.encode argument does not have any e=

Programming/scripting with "expressions - variables"
Hello to Rusers!
I am puzzled with R and I really do not know where to look
in for my problem. I am moving from SAS and I have difficulties
in translating SAS to R world. I hope I will get some hints
or pointers so I can study from there on.
I would like to do something like this. In SAS I can write
a macro as example bellow, which is afcourse a silly one but

so in data analysis.

"Special" characters in URI
Hello!
I am crossposting this to R-help and BioC, since it is relevant to both

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.

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

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
lm(y ~ 1 + effectA + effectB)
and say get parameters
intercept
effectA_1
effectA_2
effectB_1
effectB_2
effectB_3
where effectA_1 represents deviation of level A_1 from intercept and
sum(effectA_1, effectA_2) = 0 and the same for factor B.
