Since you didn't provide your data in a readable form for others, we had
to resort to other methods:

My plot has y values strictly above 200. Is that what you wanted?

Bad advice. As Duncan Murdoch just pointed out, this is inefficient.

In ggplot2 how do you justify the legend text ?
In the example below the opts(legend.text = theme_text(size =

You could try aggregate:
If we call your data frame df:
aggregate(df[2], by=df[1], FUN=min)
will get you what you asked for (if not necessarily what you need ;-)

Switching the columns around is easy enough if you need to; proceeding

Hi!
I'm definitely not an expert in R (and it's my first reply!), but if I
understand right, I think the aggregate function might do what you're
looking for.

Hello,
I´ve got a statistical problem that I hope you can help me with. It doesn´t
have to do directly with R, so if there´s another forum which would suit
better, please tell me!
Now here´s the problem:
I want to derive confidence intervals for a variable X, which is - given the

Hi Assa,
First off, please don't cross-post. This is really an R-help question,
as it is about the R language rather than a specific BioC package.

Hello,
I need to modify some huge arrays (2000 individuals x 50 000
variables).
To format the data, I think I should benefit from optimized R-selection
and R-replacement inside a matrix and prohibite a naive use of loops.
Thank you in advance for providing information about the following proble
I was looking for a fast line counter as well a while ago and ended up
writing a small function in R:
countLines() in the R.utils package
At least at the time, it was faster than readLines() [for unknown
reasons]. It is also more memory efficient. It supports connections.
I don't think it be

Looks promising, but I need something that uses connections because

Ah... the lack of c-level api for connections again ;-)

I'm trying to avoid the overhead of reading the file in twice. (I'm
trying to preallocate a data structure for a chunked read)

How about something like

dear all,
I have a problem with a masked object in a package we created here.
we make a package for a workflow of internal analysis of microarray data.
to create the package we used:

Is there a fast way to determine the number of lines in a file? I'm

What exactly is your definition of "macro"? What to you want to do?
What is the problem that you are trying to solve? Why to you think
macros will help? Typically R does not have macros; I assume that
idea is a holdover from SAS.

Dear list,
I am looking for an R-only implementation of a Nelder-Mead process that can
find local maxima of a spatially distributed variable, e.g. height, on a
spatial grid, and outputs the coordinates of the new point during each
evaluation. I have found two previous threads about this topic,
Try
shell('\"file.xls\"')
where 'file.xls' is the excel filename.
The escaped quotes (\") are not strictly necessary if the filename contains no
spaces, but they are essential if it does.
