data.frame-question]
First a general comment on posting style, could you please be more specific
about where the error occurs as without this it is very difficult to
identify what the problem is.
Now concerning your problem. When I tried the code I posted yesterday I
thought it worked fine. I've tried it again now and found that the
data.frame TAB3 actually only has one column and the names "A",

y-axis in histograms
Dear R- list,
I have some data to present with histograms. Therefore I used hist(...).
I have few values with almost 80% of
the frequencies (totaly 800) and some other values with low frequencies
( totaly 5 -10 )
that I want to emphasize. Therefore I want to "cut" the y-axis on 100,
but I
don't know how to deal with this.
Thanks in advance,

boxplots instead of a scatterplot
Dear R list,
I am a newbie to R and programming itself, so my question may be easy to
answer for you.
I wanted to create a scatterplot and i used the following code:
par(mar=c(10, 4.1,4.1,2.1))
plot(q$location,q$points, , las=2, cex.axis=0.5,xlab="", ylab="" )
#location are character strings, there are about 70 locations
#points are numeric, there are more than 4 points for

data.frame-question
Dear R-List,
I am very new to R and programming itself, so my question may be easy to
answer for you.
I tried a lot and read through the manuals, but I still have the
following problem:
I have 2 data-frames:
Number<-as.numeric (Number)
Name<-as.character (Name)
TAB1<-data.frame (Name,Number)
- it looks like this:-
Name Number

Assigning NULL to large variables is much faster than rm() - any reason why I should still use rm()?

Assigning NULL to large variables is much faster than rm() - any reason why I should still use rm()?
Hi,
in my packages/functions/code I tend to remove large temporary
variables as soon as possible, e.g. large intermediate vectors used in
iterations. I sometimes also have the habit of doing this to make it
explicit in the source code when a temporary object is no longer
needed. However, I did notice that this can add a noticeable overhead
when the rest of the iteration step does not take that

converting an ASCII file to a matrix
Dear R-WinEdit users,
I got a simple question, but somehow I cannot find the answer, although
I have
tried a lot!
I got an ASCII-file and I want to import it into R, so that every
character is defined by [i;j].
The rows are not of the same length.
the file looks like the following shortened abstract example:
name: xxxxx xxxx
age: 9.9.99
record number: 999
title: xxxxx xxxx xxx
keywords: xxx xx

ggplot2 problem
Hello all!
I have a problem with ggplot2 library. I want to do an heat map and the y
variables are the year months. If I use the following code, he y values are
in alphabetical order, but I want it in month order.
The code is:

plot()
I am an R novice trying to figure out plot().
Specifically, I am trying to plot the values of a
numeric variable V for a set of years (1970, 1974,
1976, 1978, 1980). How do I get R to label the years
I am plotting on the x-axis rather then some general
levels (1970, 1975, 1980.) Using as.character(year)
doesn't seem to help, and using as.factor(year)
generates steps insteads of dots.

I have a complex line by xy-values (ordered by z).
And I would like to get interpolated y-values on the positions of x = 0:600.
How do I get the correct points?

R and ViM
Dear all,
I'm starting to learn R, but I'm already programing for a while, using
ViM as editor. Therefore I'd like to be able to use R together with
ViM.
My question now is, whether there are already people out there knowing
how to do this in a similar easy way as with Emacs, and if those would
be willing to share this knowledge.
I did already research on the web on this topic,

Metaplot Axis Annotation
Hello,
We are looking to adjust the font size of the axis annotation on the graph
that results from use of the metaplot() function. Metaplot seems to respond
to cex and cex.lab to change those graphical parameters, but it doesn't
respond to cex.axis. Is there a way to work around this by creating a
customized x-axis, and if so, how?
Thanks for all your help. Syntax is below.

I would like to draw a "sunflowerplot" because I have data (decade by
month) that plots multiple times on the same x-y co-ordinates. Further I
would like to colour each of the points/sunflower leaves on the plot
according to the group they belong to (i.e. which type of event each
represents within that decade and month). I thought that this would be
