PageUp/Down in gnome-terminal
Dear all,
I am using gnome-terminal to run R, and I noticed that standard
PageUp/Down do not work but they do work for other programs within the
same terminal window (e.g. irssi). Scroll bar does not work either.
I run R using GNU-screen, but it doesn't seem to make any difference.
Many thanks

lower triangle of the correlation matrix with xtable
Dear all,
mydata<-data.frame(x1=c(1,4,6),x2=c(3,1,2),x3=c(2,1,3))
cor(mydata)
x1 x2 x3
x1 1.0000000 -0.5960396 0.3973597
x2 -0.5960396 1.0000000 0.5000000
x3 0.3973597 0.5000000 1.0000000
I wonder if it is possible to fill only lower triangle of this
correlation matrix? Using 'dist' doesn't seem to be useful as it doesnt
allow to convert this table

multiple R sessions from one working directory using GNU screen
Dear all,
I am using GNU screen to run multiple R sessions from one working
directory in order to split task, however I noticed that dataset is not
synchronized e.g. if I have two sessions R1 and R2, and I remove an
object from R1, R2 doesn't change as expected or change at random.
I have tried to save.image(), q() and then restart both sessions, but it
does not help.
Any suggestions?

standardize columns selectively within a dataframe
Dear all,
I have a dataframe:
df<-dataframe(a=c(1,2,3),b=c(4,5,6),c=c(7,8,9),d=c(10,11,12))
I want to obtain a new dataframe with columns a and b being standardized
((x-mean(x))/sd(x)); the other two columns (c,d) I want to leave
unchanged. What is the best way to achieve this? I have been trying to
use subscripts but did not succeed so far.
Any tips?
Many thanks,

looking into function body without package installation
Dear all,
I was wondering if there is a way to explore a syntax of particular
function without package installation?
I am trying to write my own functions, and I would like to see how
other people approached similar problems. If every time I have to
install/load package to be able to explore function syntax I end up
installing loads of packages I am never going to use.

ZINB multi-level model using MCMCglmm
Hi,
I am Olga Viedma. I am running a Zero-inflated negative binomial (ZINB) multi-level model using MCMCglmm package. I have a doubt. Can I use the "Liab" outputs as fitted data, instead of the predicted values from "predict"? The liab outputs fit very well with the observed data, whereas the predicted values are so bad.
Thanks in advance,

brtfs on Solaris? (Re: [osol-discuss] [indiana-discuss] So when are we gonna fork this sucker?)
brtfs could be supported on Opensolaris, too. IMO it could even
complement ZFS and spawn some concurrent development between both. ZFS
is too high end and works very poorly with less than 2GB while brtfs
reportedly works well with 128MB on ARM.

Call C code from R
Hello, All!
I have function which is written in C, the function uses other functions
also builded bu me. Now I need to use the function to build R function.
My questions are:
1. How can I include libraries (for example, iomanip, sstream, tcl.h)?
2. Should I put other function to the separate file and then include the
file?
Thanks All :)

decision tree finetune
My decision tree grows only with one split and based on what I see in
E-Miner it should split on more variables. How can I adjust splitting
criteria in R?
Also is there way to indicate that some variables are binary, like variable
Info_G is binary so in the results would be nice to see "2) Info_G=0"
instead of "2) Info_G<0.5".
Thank you in advance!
And thanks for Eric who

decision tree display
I am using "plot" and "text" commands to display the decision tree I built,
here is the code:
plot(fit, compress=TRUE)
text(fit, use.n=TRUE)
but the the result of this code is not readable. Text doesn't get fully
displayed (missing on the margines and overlapping in the middle). Where
can I get info on how to adjust the tree display and text size display?
Please help.

Installing Java on Centos
Hello,
I have recently tried installing Java on Centos 6.4 and have found that the
wiki tutorial for this subject is quite outdated (the proposed method
doesn't work on the new version as the spec file is outdated and there is
no need to rebuild the rpm with nosrc file anymore). I would like to post a
tutorial on installing Java on Centos that would be more up-to-date and

rpart package
Hi,
I am a brand new user and may be my question is too simple. I have R on
our (not Unix) server. I am trying to build a decision tree and the error
message says "couldn't find function rpart". Does it mean I have to ask our
server guy to install an additional package?
Thank you,

try-error within for loop
Dear all,
I run a loop wrapped in try(), and for each of the rows where
"try-error" is true I want to fill that row with NA (at the moment it is
omitted). So I would expect to get a dataframe with 1000 rows some of
which would be empty, but instead I get a dataframe with 995 rows. In
this case missing 5 rows were omitted.
Any suggestions?
Thanks,

Call C code from R
Hello, All!
I'm new for R-devel list. And I'd like to ask some questions,
maybe they will be stuped for the most part of members of the
list.
I need to call function which is written in C++ from R.
My questions are:
1. How should I include libraries (for example, iomanip,
sstream, iostream)?
2. Can I use namespace?

RV: problems for making grids from lmer models
Dear colleagues:
I am working with binary mixed models using lme4 package and everything works fine until I try to spatialize the fitted models using grids predictors. I have used the "predict" function from RASTER package and the RSAGA functionalities, but always I have the same error: "Error in object$xlevels : $ operator not defined for this S4 class".
