substituting dots in the names of the columns (sub, gsub, regexpr)
...e to know more on regexp, sub
and so on, since each time
I have strings to manipulate, I must face my ignorance in the topic of
regular expression and its syntax.
Is there any page with examples, where I can improve my knowledge and
stop being frustrated each time I have to manipulate strings?

Is it possible to modify the position of the graphic window ?
Dear R users,
is there a way to tell R where to draw the windows where the plots are
drawn ?
I always get that window on the right of my screen, where it interferes
with my Xemacs + ESS window where I'm writing lines.
Of course I can move it manually, but I would like to have it
permanently on the right, rather than on the left.
Thanks for any advice

how to combine data of several csv-files
Hello,
I'm looking for a solution for the following problem:
1) I have a folder with several csv files; each contains a set of
measurement values
2) The measurements of each file belong to a position in a two
dimensional matrix (lets say "B02.csv" belongs to position 2,2
3) The size of the matrix is fix
4) I cannot assure to have a csv file for each position
5) Each position

Prettier axis labels when using log (or exp!!) scales in Lattice (follow up)
...0e3 ~ Sepal.Width, iris,
scales=list(y=list(log=10)),
yscale.components = yscale.components.logpower)
but without transforming the variables
In summary I would like to be able to use some sort of exp(10) instead
than log(10).
Any suggestion to accomplish this?
Thanks in advance

I: a coloured band within each panel of a lattice bwplot
Hi all,
I would like to add to each panel of a bwplot a coloured central band,
centered on the mean of the values, being its width +- 2% of the mean
itself.
I know how to add lines, i.e. something like
bwplot(X ~ Y|FACTOR
data=my.df,
panel= function(x, y){
panel.bwplot(x, y)
panel.abline(v = mean(x, na.rm = T) - mean(x, na.rm = T) * 0.02
panel.abline(v =

I: differences between R and S (reproducing a plot from a book )
Dear R-Users,
I'm currently studying the book
Statistical model in S by Chambers J.M and Hastie T.J..
At page n 3 there's a plot showing the means of a variable at each of the
levels of the factors of an experiment.
I hope to be able to reproduce it here by ASCII art.

(Lattice) How to improve the readability of a bwplot, i.e. separating groups somehow
Hi all,
first of all thanks for the answer to my previous question on lattice some
time ago.
In particular to Patrick Connolly for advices on netiquette (I hope this
time I'm doing right....)
and to Deepayan Sarkar fro the help on lattice.
Now, my nowaday problem.
Please consider the following

how to skip a numeric column for averaging other columns?
Data has the first row for variable name and the first column for sample
name. I want to take "Log" for all data, but how to compute without the
first column for sample name.
That is,
column 1: sample ID
column 2-10: data
I want to find an average on each column (2-10)
> apply(raw_data,2,mean)
Error in Math.data.frame(list(sample_id = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, :

again on ubuntu 7.10 and amd64
Hi there,
this is my first post to the list.
I'm a newcomer to the linux world.
I started using it on a regular basis on May and I must say I'm quite
comfortable with it, even if I have to re-learn a lot of things.
But this is not a problem, I will improve my knowledge with time.
My main problem now is that I bought myself a new computer (described at
the end of this e-mail) and I was

Select top three values from data frame
Hi,
I'm trying to find an easy way to do this.
I want to select the top three values of a specific column in a subset
of rows in a data.frame. I'll demonstrate.
A B C
x 2 1
x 4 1
x 3 2
y 1 5
y 2 6
y 3 8
I want the top 3 values of B from the data.frame where A=X and C <2
I could extract all the rows where C<2, then sort by B, then take

indexing within the function "aggregate"
Hi all,
I'm trying to work out the following problem, but I can't imagine how.
I have the following (much reduced & oversimplified) dataset

edit.row.names taking row names from the edited dataframe
Hi all,
I am struggling to work out how to use the rownames from an edited dataframe
rather than the row names from the original dataframe. In my data set i'm
trying to extract several rows of data on particular individuals, i don't
doubt i'm using the long way round but what i have in the way of a script is

Several simple but hard tasks to do with R
Hello everybody. I've been learning R for about a month to do a
econometric study and now i'm stuck with some problems to make R do the
things I want. Here I give the list of things I wanna do from the most
simple to the more complex (for me of course):
1. Make a log. I've been using Stata and there i have a great tool to
register what the program do: the log file, wich it's a

Xemacs do not want to execute help.start() with R1.9.1
Hi all,
I 've just reinstalled from the scratch my Windows 2000 (Italian version)
