Regular expression to define contents between parentheses
...following, but this pattern seems to enclose all that is included between the first opened parenthesis and the last closed parethesis, which makes sense, but it's not what I need:
subvector<-gsub("\\((.*)\\)","",myvector
Your help will be very appreciated.
Thank you,

no applicable method for "names"
...> names(x)
Error in UseMethod("name"): no applicable method for "names"
... instead of NULL. the same is true for lists and dataframes. attr(z,
"names") is a workaround, but i don't want to change all my functions.
is this a know bug? thanks for any comments,

R console closes on its own
...save the plot as a PDF (from the
menu in the R console). I can save the PDF twice in a
row; but at the third time, right when I am about to
give a name to the graph, R crashes, no error
messages.
I am using R 2.6.2, for Windows. I copy the script
from TinnR.
Thank you in adavance for any help,
Judith

Substitution of Variables
...run a script under the variable (that
comes from a csv file) that is assigned to another
variable. This is very a simplified version of what I
want to do:
data<-read.csv('name.csv')
names(data)<-("VA","VB","VC")
v<-VA
mn(v)
Thank you in advance,

Removing Inf and Inf values from a fata frame
...when I apply
the different functions (mean, std, etc.) I create a
new data frame, the empty values generate Inf and -Inf
values. How can I remove those Inf and -Inf values
from the new data frame? I already specified na.rm in
the mean and std functions, but the values are still
there.
Thank you,

Multiple lines with a different color assigned to each line (corrected code)
Sorry, I just realized I didn't type in the correct
names of the variables I am working with, this is how
it should be:
plot(1,1,type="n")
for (i in summ$tx) {
points(summ$timep[summ$tx==i],summ$mn[summ$tx==i])
lines(summ$timep[summ$tx==i],summ$mn[summ$tx==i])
}
Thank you,

Fast question...
...the problem resides in the source data "e:/program".
Seems that rsync "doesn't understand" the string "e:", because when I
type "/cygdrive/e/program"
I can send the data without any problem...
So, has anyone tried something like this?
Thanks in advance!

Reordering levels of a factor when the factor is part of a data frame
...t;))
it won't work because df[variab] is a data frame. The reason for reordering the levels of the factor is because once that variable is plotted, the levels of the factor need to appear in certain order.
How can I re-order the levels of a factor whose name I don't know?
Thank you,

Replecing empty values with a letter (continuation)
...I hit the send botton by accident. Here is my
code so far:
dat<-read.csv('myfile.csv', na.strings="")
dat[is.na(dat]<-'N'
But it doesn't replace the <NA> for the letter 'N'.
I am using R v 2/7/0, running it under Windows
XP.
Thank you,

Ordering the levels of a vector
...levels manually:
levels(day)<-c('Day -1', 'Day something','Day
something else')
I tried as.ordered, but I guess I am not using the
right function.
How can I command the script to put the panels in the
original order given of the vector in a data frame?
Thank you,
Judith

Legend outside plotting area
Hi,
I have been trying many of the suggested options
to place a legend outside plotting area, including
something like this:
par(xpd=T,
oma=par()$oma+c(4.5,0,1.5,0),mar=par()$mar+c(1,0,1,0)
But the aspect of the four plots gets compromised
when I change the margin settings. I cannot use mtext
because I need to use colors for the text. I tried
layout, but wouldn't let me include

init script for tinc-1.1pre10
HI,
Is there an init script to start stop tinc tinc-1.1pre10 for debian.
I am running tinc -n name --pidfile /dir/name start from /etc/rc.local
sometimes it's not creating the pid file but I see the process running.
It would be great if we can manage it from /etc/init.d/
Thanks

How to mix different font styles in axis label of lattice plot?
Hello,
I have a y-axis label that reads: "S. schenckii yeast cells". The part that reads "S. schenckii" needs to be in italic style, the rest of the text is normal style. How can I specify the different font styles for each part of the y-axis label?
Thank you,
