Error Bar Issues
Hello all,
I am an undergraduate student who is having syntax issues trying to get

Break in the y-axis
Hello all,
I have been having trouble getting a break in my y-axis. All of my data
points are up around 100-200, but the graph has to start at zero, so i would
like to remove all the white space using a break symbol. I have been able
to get the break and labels to be correct, however, I can't seem to get the
data to match the axis anymore. I must be using the axis.break() in plotrix

How to plot error bars
I'm a newcomer to R. I can't seem to find any documentation how to add
error bars to points in scatter plots. I guess I could plot the points,
then compute and plot line segments in the X and/or Y directions to
represent the errors?

Help with plotting error bars in R
Hi,
I'm sorry to send email to everyone on this list, but I have a simple question
which is bothering me and I can't seem to figure out the correct answer. I
just downloaded R and I'm trying to reproduce some simple analysis I've done
on other packages. In particular, if I have a vector of experimental values
and a vector of their uncertainties, is there a way to plot the

plotCI error when trying to omit upper or lower bars (PR#7764)
Full_Name: Volker Franz
Version: 2.0.1 (2004-11-15)
OS: Mac OSX / Debian
Submission from: (NULL) (84.58.8.232)
Hi there,
the new version of plotCI (Version: 2.0.3 of gplots) produces errors
if the upper or lower error bars should be omitted by passing NULL as
an argument. Older versions of plotCI had no problem with this. Here
is an example:
library(gplots)
means <- c(1,2,3,4,5)

How to add error bars to plot(x,y)in R?
Dear R Experts,
Is there a way in R to add an error bar (say in the y direction) for each data point?
Thanks

Newbie question: Linear regression with error bars.
Hello guys,
I am a total newbie on R, having downloaded it, read the documentation and
started playing with it right now.
My general question is what 'lr' model can be used for doing a linear
regression on points that have a variance associated with them (ie. Monte
Carlo simulation results).
Actually my Data sets look like:

several plots in one
Can anyone tell me how I can supply more than one graph to plotCI
(gplots) at once?
Below is what I tried, also with rbind instead of cbind.
What is the way to do this (in general, I think)?
Problem is that lines of 1-st and 2-nd series are mixed, while they have
nothing to do with each other.
I also tried calling plotCI with argument add=TRUE, which didn't seem to
work (that is actually

Editing data sheet issue with write.table append
I'm running R 2.15.2 on Max OS X 10.6.8
If I write a simple file
Data1<-1
DF<-data.frame(Data1)
colnames(DF)<-"Col1"
and write to a csv file
write.table(DF,file="Data.csv",sep=",",row.names=FALSE,col.names=TRUE)
I can then append to it no problem
Data2<-2
Data3<-4
DF2<-data.frame(Data2)
DF3<-data.frame(Data3)

How to plot doubles series with different location using plotCI
Dear list
members,
I would
like to create two series of plotted mean values and error bars, yet with
different locations along the x-axis.
Plotting of
first series using plotCI with the standard arguments goes without any problem.
However I do not succeed to add the second series in the same plot, which
should be horizontally shifted from the first series along the x-axis. The “add=TRUE”

Problems with plotCI
Got problems with plotCI (plotrix)
I only want to plot the upper part of the error bar in my barplot
I had the exact same commands working two months ago
Now I wanted to change the legend and when I ran it again plotCI stopped

To me it seems like there must some bug in R

Hi R masters!
I need a Help with plot confidence intervals for one equation. I use
library gplots and plotCI command in this script:

plotCI(ano,rf,uiw=ciw.f)
But in the graph not shown the errors bar and I have this error msg

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

why the same values cannot be judged to be the same in R
Hi Rusers,
I found sometimes that the same values cannot be judged to be the same in
R. Anybody knows the probelm? I think i ignored some minor detail. Thanks.
Here is the example.

problem merging two data sets ( one with a header and one without)
I have two set of data, Data1 and Data2 . Data1 has a header and Data2 does
not. I would like to merge the two data sets after removing some columns
from data2 .
I am having a problem merging so I had to write and read final data and
specify the ?header=F? so the merge can be done by?V1?. Is there a way to
avoid this step. The problem is when I do cbind the FinalData has different
column names
