match and new columns
Hi Bill,
I put stringsAsFactors = FALSE
still did not work.
tdat <- read.table(textConnection("A B C Y
A12 B03 C04 0.70
A23 B05 C06 0.05
A14 B06 C07 1.20
A25 A23 A12 3.51
A16 A25 A14 2,16"),header = TRUE ,stringsAsFactors = FALSE)
tdat$D <- 0
tdat$E <- 0
tdat$D <- (ifelse(tdat$B %in% tdat$A, tdat$A[tdat$B], 0))
tdat$E <- (ifelse(tdat$B %in% tdat$A, tdat$A[tdat$C], 0))

Hello,
Here is one way.
tdat$D <- ifelse(tdat$B %in% tdat$A, tdat$A[tdat$B], 0)
tdat$E <- ifelse(tdat$B %in% tdat$A, tdat$A[tdat$C], 0)
Hope this helps,

Thank you Rui,
I did not get the desired result. Here is the output from your script

Use the stringsAsFactors=FALSE argument to read.table when
making your data.frame - factors are getting in your way here.

Accuracy: Correct sums in rowSums(), colSums() (PR#6196)
Full_Name: Nick Efthymiou
Version: R1.5.0 and above
OS: Red Hat Linux
Submission from: (NULL) (162.93.14.73)
With the introduction of the functions rowSums(), colSums(), rowMeans() and
colMeans() in R1.5.0, function "SEXP do_colsum(SEXP call, SEXP op, SEXP args,
SEXP rho)" was added to perform the fast summations. We have an excellent

Create a list object in a loop
Dear all,
I'm trying to create a list of point patterns ppp.object {spatstat} in a loop.
My dataset looks like this:

[1] "EID" "latitude" "longitude" "month" "year" "CPUE" "TSUM"
[8] "fTSUM"

Thank you Bert and Jim,
Jim, FYI , I have an error message generated as
Error in allstates : object 'allstates' not found
Bert, it is working. However, If I want to chose to include only mos years
example, 2003,2004,2007 and continue the analysis as before. Where should
I define the years to get as follow.
2003 2004 2007

Ternaryplot as an inset graph
Hello
I am trying to add a ternary plot as a corner inset graph to a larger
main ternary plot. I have successfully used add.scatter in the past for
different kinds of plots but It doesn't seem to work for this particular
function. It overlays the old plot rather than plotting as an inset.
Here is a simple version of what I'm trying. Note that if I change the
inset plot to be an ordinary

npudens(np) Error missing value where TRUE/FALSE needed
Hi,
I am looking for some help concerning the npudens function
in the np package.
I am trying to find a kernel density function of a
multivariate dataset and the density evaluated at each of the 176 points.
I have 2 continuous and 3 ordered discrete variables. My
sample size is 176.
So edata is a 176x(2+3) data frame, while tdat is a 1x(2+3)
vector.
bw_cx[i,] is a 1x (2+3) vector

Bootstrap ICC estimate with nested data
I would appreciate some thoughts on using the bootstrap functions in the
library "bootstrap" to estimate confidence intervals of ICC values
calculated in lme.
In lme, the ICC is calculated as tau/(tau+sigma-squared). So, for instance
the ICC in the following example is 0.116:
> tmod<-lme(CINISMO~1,random=~1|IDGRUP,data=TDAT)
> VarCorr(tmod)
IDGRUP = pdLogChol(1)

xyplot() with segments() superposed?
In the hypothetical example below, how do I add two segments() into
the two panels, respectively? Say segments(x0=5, y0=10, x1=5, y1=20)
on the left and segments(x0=15, y0=-10, x1=15, y1=-2) on the right?
Many thanks in advance,
Yuelin Li.
ps. part of the code came from a solution given by Deepayan Sarkar.

problem with cut.Date/date plotting in ggplot2
I've hit a problem in ggplot2 which I can trace back to cut.Date ,
which is either a bug or (??) ggplot2 trying to do something it
shouldn't with cut.Date (although its use of cut.Date seems OK).
Apparently any (?) call of the form
cut(as.Date("2008-07-07"),"weeks")
where the date *begins the week*, gives the error
Error in 1:(1 + max(which(breaks < maxx))) :

R package 'np' problems
Hi List,
I'm trying to get a density estimate for a point of interest from an npudens
object created for a sample of points. I'm working with 4 variables in total
(3 continuous and 1 unordered discrete - the discrete variable is the
character column in training.csv). When I try to evaluate the density for a
point that was not used in the training dataset, and when I extract the

nmle: gnls freezes on difficult case
Hi,
I am not sure this is a bug but I can repeat it, The functions and data
are below.
I know this is nasty data, and it is very questionable whether a 4pl
model
is appropriate, but it is data fed to an automated tool and I would
have hoped for an error. Does this repeat for anyone else?

S3 generic method dispatch on promises
Dear R friends
I wanted a function to make a simple percent table that would be easy for
students to use. The goal originally was to have a simple thing people
would call like this
pctable(rowvar, colvar, data)
and the things "rowvar" and "colvar" might be names of variables in data. I
wanted to avoid the usage of "with" (as we now see in the table help).
Then
