FAQ 7.31 is probably the answer. If you want to try it, convert all
your numerics that you want to merge on to character and round to the
same value so you can "see" what is actually being matched. Comparing

I frequently use R's help facilities and I know about the asp argument to
plot, but this doesn't answer my question. I would like to allow the aspect
to be determined automatically but *query* the aspect ratio for future use.
I suppose one work-around would be to use the data ranges and plot regi
Many thanks to all for resolving my issue!

I have a dataset that I'm trying to rearrange for a repeated measures analysis:

I suspect reshape() is the function you're looking for; there is also a
reshape package that you might prefer.
It's also quite easy to do this in base R using unlist() and some indexing
with rep, but that may be more than you care to deal with.

I have a vector of gene symbols, some of which have multiple aliases. In the
case of an alias, they are separated by ' \\\ '.
Here is a real world example, which would represent one element of my
vector:
Eif4g2 /// Eif4g2-ps1 /// LOC678831
What I would like to do is input the vector into a functio
You need a escape before each backslash:
a <- c('a \\ b', 'a \\ b')
cat(a, "\n")
You can write in this form:
strsplit(a, " .*\\.* ")

For posterity's sake, here is the solution I figured out. Putting the
following lines after the plot(f) command seems to set the angle correctly:
myasp <-
(par("fin")[2]-par("mai")[1]-par("mai")[3])/(par("fin")[1]-par("mai")[2]-par("mai")[4])
(f_angle <- atan(myasp)*180/pi)
(g_angle <- atan(2*mya
Thanks Henrique. I had actually tried using 6 back-slashes but didn't know
to use 'cat' to see the non-escaped representation (see below to see my
original confusion). Your strsplit, of course, works great. Thanks again!

The ramps package looks very appealing. I have run the examples in the
package .pdf and gone through the .pdf article at the Journal of Statistical
Software, and am very impressed. Is it possible to see a spatio-temporal
example in R script as well? Thanks.

Hi,
I have a population. Then I have picked one relatively small sub-sample of it
using a particular criterion. The means of the whole population and that of the
sample seems to differ significantly. The distributions are not normal. What is
the right test?

Hi,
I generated a 3-column heatmap, however, I want to have a smaller column
width and big font size of label on the right side.
Thanks!

Dear R-Help subsribers,
upon running into a wonderful ggplot2 package by accident, I abruptly
encountered another problem. Almost every command run with ggplot2 results
in some sort of error. The one below is far the most common one. Kind people
from ggplot2 mailing list couldn't manage to solve
Dear Sir,

Thanks a lot for your solution and guidance. It worked wonderfully.
