Recoding using the memisc package
Dear All,
I am trying to recode a variable using the functions provided by

c=3,

recover masked functions?
Hi,
I have loaded the packages car, memisc, Hmisc and all
of these implement the function recode. The order in
which the packages are loaded depends on the order I
execute my scripts and thus is not always the same and
the syntax of the recode function changes with the
package.
Is there any way to call specificly the memisc recode
function?
Or maybe it's better to detach all packages first

Recode of text variables
Hi all
I am trying to do a simple recode which I am stumbling on. I figure
there must be any easy way but haven't come across it.
Given data of A","B","C","D","E","A" it would be nice to recode this
into say three categories ie A and B becomes "Treat1", C becomes "Treat
2" and E becomes "Treat 3".

Seeking help with an apparently simple recoding problem
Hello,
I have struggled, for longer than I care to admit, with this seemingly simple problem, but I cannot find a solution other than the use of long drawn out ifelse statements. I know there has to be a better way. Here is stripped down version of the situation:
I start with:
a <- c(1,0,1,0,0,0,0)
b <- c(1,1,1,1,0,0,0)
c <- c(1,1,0,1,0,0,0)
rbind(a,b,c)

Conditional recoding
I am trying to recode a variable into another variable and while the package
'car' works well when it is only recoding A into B, I am not sure I can do
the same with recoding (A or C) into B. If i can use recode please advise on
how to. So i am using an if/else if conditions.
My sample dataset is below along with the code and the warning and results i
get.
TIA

[OT] Open source archive program on windows
I am looking for a recommendation for an open source competitor to Winzip.
I seem to recall Brian Ripley mentioning one in the last year or so, but
couldn't find it in the mail archives. (Searching on Ripley there is
somehow not terribly useful.)
Suggestions?

Automatic Recoding
I have a text file full of numbers (it's a edgelist for a graph) and I would like to recode the numbers as they are way too big to work with. So for instance the following:

676529098667 100867672856227

676529098667 98928373
1092837363526 716172829
would become:

Some people have suggested placing new limits on foreign

American exports.
Do you FAVOR or OPPOSE placing new limits on imports, or

numeric variables converted to character when recoding missing values
Dear R helpers,
I have a data frame where missing values for numeric variables are coded as
999. I want to recode those as NAs. The following only partially succeeds
because numeric variables are converted to character in the process:
df <- data.frame(a=c(999,1,999,2), b=LETTERS[1:4])
is.na(df[2,1]) <- TRUE
df
a b
1 999 A
2 NA B
3 999 C
4 2 D
is.numeric(df$a)
[1] TRUE

how to recode in my dataset?
Dear Rusers,
My question is about "recode variables". First, i'd like to say
something about the idea of recoding:
My dataset have three variables:type,soiltem and airtem,which means
grass type, soil temperature and air temperature. As we all known, the
change of air temperature is greater than soil temperature,so the
values in those two different temperaturemay represent different

R programming style
I am aware of one (unofficial) guide to style for R programming:
http://www1.maths.lth.se/help/R/RCC/
from Henrik Bengtsson.
Can anyone provide further pointers to good style?
Views on Bengtsson's ideas would interest me as well.

Cygwin and Rtools
I have just got a new machine and had a basic cygwin installed before it
was given to me. It didn't include make. Previously I have installed
Rtools to build packages and now I have got myself a bit confused as to
whether to just install make from the cygwin packages or to install
rtools. I would welcome any advice. I had a look at the rtools section in
the Administration Manual and the
