Hi. I have been making sample data sets to learn how to use R Commander, and

You can not import xls file by read.table. You may save xls as csv
file, and import it by read.csv.

Not knowing the package or the function. Could the round() function help
you? Or do you mean decimals shown in a plot?

Thank you Gabor Grothendieck for your answer !!

Hi Everyone,
Concerning the maptools package and get.Pcent() to get polygon centroids, does
somebody know how to define the number of returned decimal places?
Thanks a lot in advance.

I suspect that your problem is that
you didn't put in a second backslash to
escape the backslash in your path.
('The R Inferno' talks about backslashes
if this doesn't make sense to you.)
'The R Inferno' also would have said that
it was very good of you to show the actual

I believe R does system calls from its current working directory
(getwd() will tell you where that is). This may not be the same
directory you designed your .bat for. What if you use the full path
for your files in the batch file? e.g.
call K:\nmvi\nmfe6 "K:\nmvi\path\control.txt" "K:\nmvi\path\out
I am trying to get the function "Models" to work each time there is an
instance of k. This code will stop after the first model is complete. I need
it to come back and pass the next value of c into the "Initial.State"
function. any ideas?

Hello,
I have made an R script that prepares a NONMEM dataset and I would like
to start the NONMEM run right after the dataset is ready.
I am using windows XP, R 2.9.1 and NONMEM 6.
I have prepared a run.bat file that looks like this:
call K:\nmvi\NMdi
Yes it does! Thank you Erik!
I had not thought about searching under 'trellis'!

Perhaps
intersect()
or
merge()
will help. But, like others, I find it difficult to understand
exactly what you want. I'd suggest providing a short example with
actual ID values.

Hello,
The version 0.0-3 of the parser package has been published to CRAN a few

The package defines a parser for R code very similar to the "parse"

Alex,
Does changing the color argument of the default theme associated with the
device to what you want?
See the "color" argument in ?trellis.device.
As an example, try the following with and without the "trellis.device" call...
trellis.device(color = FALSE)
dotplot(t(USPersonalExpenditure)
Something like this should work:
tmp <- as.Numeric(Delta)
tmp3 <- tmp[ -c(1,2)] ## elements 3 through
last (the "i" in the loop)
tmp2 <- tmp[ -c(1,length(tmp)) ] ## elements 2 through next
to last (the "i-1" in the loop)
mysum <- sum( tmp3[tmp3 > tmp2]) ##
the problem in my case is that some of the cells in dataframe$ID contain
multiple IDs, but in list$ID there is only one ID in each cell, so some of
the IDs cannot be matched if using the fucntion 'match' or '%in%'

Take a look on the package bellow. rowSds, colSds and much more.

Did you try already try:

points(ellipsePoints(2,5, alpha = 60), asp=1,col='red')
?

Doubtful. The OP did have spaces in his header. but by specifying that
only tabs should be used as delimiters the default parameters to both
read.table and read.csv would have converted the spaces to periods.
