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).
1) For this I'm factoring the data (xdata00 varies from 0 to max(xdata00))

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

Error bars
Hi,
Can anyone help with plotting vertical error bars on a bar graph.
I have tried following examples online and in the big R book and writing my own function but I have been unsuccessful and don’t really have an understanding of what it is I am doing. I have calculated my standard errors so basically just need to draw the bars on the graph but just don’t have a clue!!!
I don’t even know what

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

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

break error bars in ggplot2
Hello,
i use ggplot to plot some measures including CIs as horizontal errorbars. I get an error when the scale limits are narrower than the boundaries of the error bar and hence the CIs are not plotted.

df <- data.frame(resp=c(1,2), k=c(1,2), se=c(1,2))
ggplot(df, aes(resp,y=k)) + geom_point() + geom_errorbarh(aes(xmax = resp + se, xmin = resp - se)) +

Errbar()-function, cap and logarithmic scaling

If I use the errbar-function and have a logarithmic scale on the x-axis,
then the little horizontal bars at the end of the errbars (cap)
disappear. What can I do?
Thanks for helping!

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

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:

Rsite-searching led me to the functions 'errbar' and 'plotCI' in the Hmisc,
gregmisc, and plotrix packages. As I understand the descriptions and examples,

ggplot2, 'se' variable in geom_errorbar's limits?
Dear R-list
I'm working with with geom_errorbar; specifically I'm trying to
reproduce the example Hadley Wickham have on

between the points.
What confuses me is the 'limits' he defines for the errorbars from the

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

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

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
