Aggregate to find majority level of a factor
I want to use the aggregate function to summarize data by a factor (my
field plots), but I want the summary to be the majority level of another
factor.
For example, given the dataframe:
Plot1 big
Plot1 big
Plot1 small
Plot2 big
Plot2 small
Plot2 small
Plot3 small
Plot3 small
Plot3 small
My desired result would be:
Plot1 big

Hi,
this is not a new doubt, but is a doubt that I cant find a good response.
Look this output:

multiple plots in R
Hi, I just try to draw multiple plots in one page using R, I used par
command. For example I have 7 plots, but instead of arranging them in
the default way
plot1 plot2 plot3
plot4 plot5 plot6
plot7
I want them in this order
plot1 plot2 plot3
plot4 plot5 plot6
plot7
Could somebody tell me how to do this, please? Thanks so many.

Sweave and/or beamer issue
Dear Friends,
I not sure whether this is an Sweave or a beamer problem.

if-else function
Hi R people!
I am looking for some suggestions writing an if-else function.
The idea is to characterize different plots containing counts of
variables (here parasites). If a plot has a count equal or higher than
4 for any parasite the function should return a 1 else a 0. Later I
can loop the function over all plots.
Here I have a little subset of my data:

Repeat elements of matrix based on vector counts
I have two dataframes (df) that share a column header ("plot.id"). In the
1st df, "plot.id" records are repeated a variable number of times based on
the number of trees monitored within each plot. The 2nd df only has a
single record for each "plot.id", and contains a variable named "load" that
is collected at the plot-level and is only listed once per plot

Lattice and Beamer
Two things I think are some of the best developments in statistics and production are the lattice package and the beamer class for presentation in Latex. One thing I have not become very good at is properly sizing my visuals to look good in a presentation.
For instance, I have the following code that creates a nice plot (sorry, cannot provide reproducible data).

subset dataframe by rows using character vector?
Dear List,
I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out.
I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command.

averaging two tables (rows with columns)
Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think.
I have very big data but I have created a hypothetical data for simplification.
for example
I have : table 1

multiple plots in single frame: 2 upper, 1 lower
Hi,
par(mfrow = c(2,2))
will create a 2x2 window that I can use to plot 4 diferent figures in:
[plot1 plot2]
[plot3 plot4]
But how can do 3 so that the bottom spans the width of the upper two:
[plot1 plot1]
[p l o t 3]
Is this possible in R?

Lattice equivalent of par(mfrow = )
Dear r-helpers,
Does anyone have a straightforward example of putting together three
unrelated (expect for a common y-axis) xyplot() figures in what would
be in base graphics a par(mfrow = c(1, 3)) arrangement?

How to remove the vertical space between two graps
Hi,
I have created a barplot using the following code.
a<-c(11,23,15,34,42,31)
m<-matrix(a,nrow=2)
m[2,]<-(-1)*m[2,]
par(mar=c(4,4,4,0))
barplot(m[2,],horiz=T)
par(mar=c(4,0,4,2))
barplot(m[1,],horiz=T,col="black")
and the plot obtained is shown in "plot1.tiff".
I was not willing to see the gap (vertical space) between two graphs.
How can I achieve it?

unexpected postscript output with par(mfg)
Hi, a colleague of mine encountered some unexpected behavior regarding
the postscript output from R. It's difficult for me to tell whether
or not this is an R problem or a ghostview/gv/interpreter problem.
Just to note, I think it's exactly the same situation reported here:

Cross-validating two matrices

welcome.
Thanks,

below) and a plot by species matrix (Matrix 2 below), is there a
straightforward way to prune one matrix so that the species list

I need to save a series of lattice plots as a PDF,

Plot from a jpeg
Hi all,
I know that I can for instance draw to plots in one using
nf<-layout(matrix(c(1,2),1,2,byrow=FALSE))
Imagine I have 3 files:
plot1.jpeg
plot2.jpeg
plot3.jpeg
Anyone knows if I can read them and put on one colum and three rows reading
directly from the jpeg file?
Many Thanks

0-only-rows in correspondence analysis

I am looking for a workaround of "species empty" plots in a correspondence

I have species (abs./pres) in columns and sites in rows

Thin frame line around R pdf output in LaTeX
I'm using R 2.7 on an Intel MAC.
When I produce a pdf graph, I save the output window from the menu to a pdf file. This gives a very nice quality graph.
However when I include the graph in a LaTeX document (actually beamer presentation) using \includegraphics I get a graphic with a very light framebox around the outside. Note, I'm not using a fbox command in LaTeX.
Not sure if this is
