how to use 'points' function to plot two curves with errbar
Dear R Users,
I am using R on windows.

abline outside of plot region
Hi R people.
I ran into this problem: I created a plot with errbars, like this:
> errbar(x=c(1,2,3,4), y=c(2,1,3,3), yminus=c(1.5,0.5,2.5,2.5),
yplus=c(2.5,1.5,3.5,3.5))
Next, I wanted to accentuate some x value with an abline, like this:
> abline(v=2)
In one of my R sessions (which admittedly I have had open for quite a while
now), the abline draws outside of the plotting region

error bars
Hello R-help,
I am using R version 2.15.1.
I upgraded from R version 2.13 a few months back.
Previously, I was able to plot error bars on an xy scatter plot using the errbar function:
errbar(RAEthylene$TIME,RAEthylene$AVE,RAEthylene$AVE+RAEthylene$STD,RAEthylene$AVE-RAEthylene$STD,add = TRUE,lty=2,pch=17);
Today, I went to update my plot.
However, in R version 2.15.1 I get error code

Titles - main and subtitle won't plot with errbar
Hi, I'm struggling with errbar graphics.
I'm trying to plot an x-y graph with correct labelling, however can't seem
to get main and sub to show on my graph.
They do work when I use title(main="," etc...., but this will make it look
at lot messier,I'll have to blank out ylab=" " , and I need to try and get
the titles to update automatically according to my

Hmisc errbar color
Is there an easy way to make the error bars the same color as the points and lines they are plotted with.
My example

x=sample(1:10, 100, replace =T)
y = rnorm(100) + runif(100)
df=data.frame(x,y)
# summarize data
m = aggregate(df,list(x),mean)

plotting RR, 95% CI as table and figure in same plot
Hi all--
I am in the process of helping colleagues write up a ms in which we fit
zero-inflated Poisson models. I would prefer plotting the rate ratios
and 95% CI (as I've found Gelman and others convincing about plotting
tables...), but our journals usually like the numbers themselves.
Thus, I'm looking at a recent JAMA article in which both numbers and
dotplot of RR and 95% CI are

plot arguments (PR#14063)
Hi there,
I have recently updated to ver 2.10 (windows - I'm running xp) and find I am
having problems with plot arguments, for e.g.
Using the errbar function the error bars are now in black despite col="red",
the central point is in red though. Axis labels are drawn but not the 'main'
title. No errors are reported.

parsing numbers from a string
Dear R-help members,
I have several large data sets from certain simulations I did and now I want to plot the results nicely.
I don't know anything about the size of the x and y values in advance.
Plotting these values is not a problem.
However, I want to add errorbars (errbar in the Hmisc package).

Neat way of using R for pivoting?
Hi,
I'd like to use R to do what excel pivot tables do, and plot results.
I've never used R before, and I've managed to do something, but it's quite a
lot of code to do something simple. I can't help but think I'm not "Doing it
the R way".
I could be using R for the wrong thing, in which case, please tell me off.
I was hoping something like plot(by(t,

Plotting error bars in xy-direction
Dear R-help,
I am looking for a function that will plot error bars in x- or y-direction (or
both), the same as the Gnuplot function 'plot' can achieve with:
plot "file.dat" with xyerrorbars,...
Rsite-searching led me to the functions 'errbar' and 'plotCI' in the Hmisc,
gregmisc, and plotrix packages. As I understand the descriptions and examples,

Adding error bars to xyplot()
Hi,
I want to add error bars to a plot generated with xyplot. I've tried
both errbar() and plotCI(), but in both cases the points are not in the
same place. It's as if the two functions are using a different frame of
reference for the plotting area.
for example:
means <- c(92.5, 92.25, 90.9, 91.0, 94.15, 90.05) #means
time <- c(1,1,2,2,3,3) #occasion variable

Multiple error bar plots
Dear R-lister
I have a question about how to create multiple error bar plots.
I found that I can use an "errbar" function from Hmisc package to create one
error bar plot in which there are multiple data points (x, y) with the error
bars. Thus, I know that I can get "one" error bar plot which consists of
many data points. However, I did not find a way to put

random forest -optimising mtry
Dear R-helpers,
I'm working on mass spectra in randomForest/R, and following the
recommendations for the case of noisy variables, I don't want to use the
default mtry (sqrt of nvariables), but I'm not sure up to which
proportion mtry/nvariables it makes sense to increase mtry without
"overtuning" RF.
Let me tell my example: I have 106 spectra belonging to 4 classes, the

scatter plot with 1 standard deviation for each point
Hi,
Could anyone give suggestions how to plot a scatter plot with 1 standard
deviation for each point. To make it clearer, here is a simple example: the
scatterplot is plot(X, Y), but I want to add 1 standard deviation according
to the value of Z for each Y.

plotting derived values not raw
I am trying to plot the mean and standard error of three separate
conditions. For various reasons, I do not have access to the raw data from
which the mean and error were derived and would like to make error bar plots
utilizing only the actual mean and standard error values. Is there a way to
do this in R? Thanks for any help in advance.

errorbar il lattice plot
Hi Everyone,
I would like to add errorbars to a lattice plot. I already have a function that
adds error bars to a plot (originally written by George Gilchrist) which takes
as arguments the coordinates of the point and then the size of the error bar. I
would like to integrate it in my lattice code but I seem to be stumped.
I can put the error bar function inside my code as if it were a panel

Can levelplot colorkeys display a logarithmic scale evenly?
I'm using the {lattice} "levelplot" function to make a (more or less) 2-d
histogram, and for the most part it's working fine with my data. However, I
can't get the color key to do what I need. I can give it labels and custom
cutoffs, but my cutoff lines (and hence my labels) aren't evenly spaced, instead
they're more-or-less logarithmic, starting at
