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
Plot2 small
Plot3 small

this is not a new doubt, but is a doubt that I cant find a good response.

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:

Function for translation of a list into a matrix as used by ordination?
Hello.
Does anyone know of an existing function that takes a list in the form of:
Plot1 Species1 Abundance1
Plot1 Species2 Abundance2
Plot2 Species1 Abundance1
Plot2 Species3 Abundance3
.
.
.
PlotN SpeciesN AbundanceN
and translates into a matrix in the form of
Species1 Species2.... SpeciesN

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.

tick mark intervals
Hi everyone!
This must be a common question but I have not found an answer to it in the
archives yet.
I am producing four plots with par(mfrow=c(2,2)). The x-axis is the same for
all of them but the y-axis is different.
What I would like to do is to have a different range of the y-axis and
different intervals between tick marks. BUT
I would like to have the same number of tick marks and I would

Skipping panels in Lattice
Dear all,
I wish to generate a lattice boxplot which skips an empty cell in a design.
I have trawled r-help, scruitinized xyplot(lattice) help page, and merrily
reproduced examples of using skip from a couple of previous r-help queries
and the example given in Pinheiro & Bates. But I must be missing something...
Here's an example (running R 1.9.1 on Win2k):

R 2.6 and library(survival)
Hi all,
I have installed in R 2.6 the survival package and I am trying to analyze some
data and present plots. The problem occurs when I try to plot lines on
the same plot. E.g. take simulated data for time (t), event (e) and groups
(group1 and group2) and do:
### this is how I create the plots
plot1<-survfit(Surv(t,e)~ as.factor(group1))
plot2<-survfit(Surv(t,e)~ as.factor(group2))

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

plot focus
I am doing calculations in a loop and then plotting the results by adding a
point to each of 2 charts at the end of the loop. Its very informative as
you can see the progression through time.
My problem is, if I have 2 plots, I don't know how to get the focus back to
the first plot.
layout(matrix(c(1,2)))
plot(iris[,1],col="red",) #plot1
plot(iris[,3],col="blue") #plot2

ggplot - Setting the y-scale in a bar plot
Dear All (probably Hadley),
I am now trying to customise some plots using a bar geom.
I do not want to use the default binning statistic, but rather
calculate the bar heigths separately. I do manage this, but for
comparison purposes I would like to have a set of plots all with the
same y-axis height. But I do not seem to find out how to fix the
scale of the y-axis in this case.
Any tips?

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.

beamer overlays with Sweave?
This may be asking too much, but I'm wondering if anyone has a
solution (even a hack) for creating multiple (overlay) plots in an
Sweave file and post-processing the overlays in beamer appropriately.
For example, suppose I have a series of figure blocks in my .Rnw file:
<<plot1,fig=TRUE>>=
[stuff]
@
<<plot2,fig=TRUE>>=
[stuff]

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:

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?

Same color key for multiple lattice contour plots
Hi all,
I'm trying to make multiple lattice contour plots which have the same color
key, to allow good comparisons. However, I run into some problems when
fitting the plots to the color key. Basically my strategy to tackle this
problem was:
1) define a color key for all plots;
2) calculate the variable range for each plot;
3) calculate the range of colors from the color key that correspond

Replay recorded plot with new layout
Folks,
Please help with a graphics problem, I am running R2.4.0 on Windows XP.
In much earlier version of R (1.3? about December 2001)
I could

plot1<-recordPlot()
plot(2,2,xlab="X2",ylab="Y2")
plot2<-recordPlot()

how to add point and label to boxplot using bwplot
Hi.
My data contains information for 10 hospitals for 12 different measures.
Let's call it x1-x12. I need to create a boxplot for each one of this
measures and put them into one page. Each plot also needs to be independent,
i.e. cannot use the group feature because of different scales for each
measure. I was successful using the following code:
x1 <- c(1.317604376, 0.978038233,

Problems in "plot.lm" with option "which=5"
Hi:
I think I found an error in plot.lm with the option which=5, of course I can be wrong , as usually happen, but I had work on it for a while and show it to some other people that work with R, and so far I don't see what I can be interpreting wrong. I also worked over the plot.lm's code and change some lines to get what I call "the right plot", if any body is
