Discrete values in levelplot?
Dear all,
I am trying represent a matrix of discrete values. At the moment I am using levelplot from the lattice package, but it seems to only work with numerical values. Is there an option in levelplot that will allow me to assign a color to a discrete value, or another package that will do the same?
To clarify, with levelplot I can represent a matrix such as:
[,1] [,2] [,3] [,4]
[1,]

First call to constructor fails (R.oo)
Hi all,
I'm trying to do some object-oriented programming in R using the R.oo
package.
Right from the start I encountered a strange (at least for me) problem. I
define a new class/constructor based on the R.oo documentation.
However the first attempt to create an object fails:
=== Code: ===
library(R.oo);
setConstructorS3("MyClass",function(param) {
print(param);

Convert ASCII string to Decimal in R (vice versa) was: Hex
Hi Dieter,
Sorry my mistake. I wanted to convert them
into Decimal (not Hexadecimal).
Given this string, the desired answer follows:
> ascii_str <- "ORQ>IK"
79 82 81 62 73 75
> ascii_str2 <- "FDC"
70 68 67

ASCII map?
Is there a way to convert between and integer and a character and vice
versa? For instance
i <- 65;
ch <- intToChar(i); # "A"
i <- charToInt(ch); # 65
or even better
i <- c(65, 66);
ch <- intToChar(i); # c("A", "B")
i <- charToInt(ch); # c(65, 66)
I have tried to do a ASCII map myself, and I figured out that the ASCII

How to relocate $HOME directory
Hi there,
As you know, $HOME is generally located at "/home/$username" by default.
I would like to re-locate all users' $HOME directories to something like
"/export/home/$username" without having a hassle/trouble.
Initially, I've thought of just copying them to the new directory (under
/export/home/xxx), but guessed it might trouble for the normal use (I'm

Help needed! Error in setwd(newdir) : cannot change working directory
Hi Guys,
I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory.
I googled a little bit and tried all fixes/suggestions with no success.
Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

create new column with colnames resulting from paste()
Dear UseRs,
I would like to know the way to create a new column by naming it

For example, in for() loop I want to create columns named as
paste("test", i, sep = ""), as shown below.

dt <- data.frame(a = c(1, 2, 3), b = c(3, 2, 2), c = c(1, 3, 5))

Can you please help?

I would like to know the way of deleting NA in list().
Following is a example.

R-3.2.4 Mac/Linux different in < on characters

using par funtions in bargraph.CI()
I'm trying to create a bargraph of means with standard error bars using the
function bargraph.CI (in the sciplot package). Like this:

However, an error message comes up when I try to use the par funtion. Does
the character font/style need to be changed in a different way for this

list of funtions
Hi,
I have a function called fitMicroProtein which takes a value called
form, this can be any integer from 0-38.
In a larger function I'm making (it's called Newton), the first thing
I want to do is construct a list of functions where form is already
set. So in pseudocode
fs[[1]](...) <- fitMicroProtein(form=0,...)
fs[[2]](...) <- fitMicroProtein(form=1,...)
.

Can asterisk be run as non root anymore?
safe_asterisk used to work fine but with v1.0.3 I am getting all kinds of
permission errors, intermittant failures, etc. Even with file permissions
relaxed and ownership set to asterisk it craps out. Seems to work fine
when run as root. Comments???

cvs stable and 1.0.5
I see that 1.0.5 is out. I thought that if I am tracking cvs v1.0.x I would
always get the newest releases. However, I just did a fresh update and
install from cvs stable and it reports as only being v1.0.3.
Should I just be using the tarballs rather than the cvs -r 1_0? Or maybe my
initial cvs was incorrect?
Thanks!

rawToChar(raw(0))
Hi,
right now we have (on R v2.7.0 patched (2008-04-23 r45466)) that:
> rawToChar(raw(0))
[1] ""
> rawToChar(raw(0), multiple=TRUE)
character(0)
Is this intended or should both return character(0)? Personally, I
would prefer that an empty input vector returns an empty output
vector. Same should then apply to charToRaw(), but right now we get:

R 2.7.0, match() and strings containing \0 - bug?
Hi,
A piece of my code that uses readBin() to read a certain file type is
behaving strangely with R 2.7.0. This seems to be because of a failure
to match() strings after using rawToChar() when the original was
terminated with a "\0" character. Direct equality testing with ==
still works as expected. I can reproduce this as follows:
> x <- "foo"
> y <-
