Moving from S-plus to R I encountered many great

Currently, I am left with 2 problems that are
handled differently:
1) I did lots of overplots in S-Plus using
par(new=T,xaxs='d',yaxs='d') to fix the axes
I am trying to clean up some dates and I am clearly
doing something wrong. I have laid out an example
that seems to show what is happening with the real
data. The coding is lousy but it looks like it
should have worked.
Can anyone suggest a) why I am getting that NA
appearing after the
column in the
dataframe but an array of rownames ( I don't know how
they are stored).
I think you can do the same thing as you did for the
data.frame but as I say, I am not sure I understand
the question. Would you post a little example?

Why? The question is not clear and could mean several

thanks, that works
There are a couple of ways but I think you need to
read about R . Have a look at Managing data
http://cran.r-project.org/doc/contrib/Lemon-kickstart/index.html
and / or read the Intro to R manual available on CRAN
or probably from the R help icon.
you have a data.frame DF you can assign names

Hi,
I wonder whether R can finish the following project:
I want to make a chart to represent 10 genes. Each
gene has orientation and length. Therefore, a gene
can be represented by arrows.
Can R be used to draw 10 arrows in one line ?

hello
what do i write for R to recognize both columns?
In the R-script downunder you can see that i use
tapply to get my
information out of my data, and then i need to use
it as a dataframe
with both columns! It is like R is using the first
R considers Mazda RX4 Wag to be three columns. There
fore you have 6 columns of data and only 6 names.
Use like this
Mazda RX4 and Mazda Rx4 Wag to indicate each is a
single character value.

Probably a very easy question, but I was wondering
whether or not it is
possible to calculate the per-row (or per-column)
minima and maxima for
