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)

Y error bars, dates on the X-axis
Dear forum,
Does anyone know any functions for plotting vertical error bars, if the
x-axis variable is a date?
I can produce a pretty plot with dates on the x-axis, if I don't want to
include error bars. I can also produce a nice plot with error bars, if I
just use Julian days for the x-axis, but I'd much rather have the actual
dates.
I have tried writing my own function, plotCI

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

error bars in matplot
Hi,
I was trying to get error bars in my matplot. I looked at an earlier thread, and the sample code that I made is:
#------------------
library(plotrix)
mat1 <- matrix(sample(1:30,10),nrow=5,ncol=2)
ses <- matrix(sample(1:3,10,replace=T),nrow=5,ncol=2)
vect <- seq(20,100,20)
rownames(mat1) <- rownames(ses) <- vect
colnames(mat1) <- colnames(ses) <- letters[1:2]

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?

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.

graphing with error bars
I am not able to find information about doing line plots with error bars in the R- help information.
Would someone like to tell me if this can be done in R and either get me started or lead me
to information about how to do the error bars?
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:

Using known errors and error bars
Hi,
I'm now to R and hope (actually, I'm quite sure) you can help me. I made
an experiment and measured two values. As I know the errors of these
values I want to use them with the linear regression,
eg
Value A
1.1+-0.02
1.9+-0.05
3.05+-0.03
4.0+-0.01
5.1+-0.06
Value B
4.2+-0.14
5.3+-0.05
6.8+-0.11
7.9+-0.01
8.5+-0.02
lm(B~A) does the linear regression but how can I

Systematically biased count data regression model
Dear all,
I am attempting to explain patterns of arthropod family richness
(count data) using a regression model. It seems to be able to do a
pretty good job as an explanatory model (i.e. demonstrating
relationships between dependent and independent variables), but it has
systematic problems as a predictive model: It is biased high at low
observed values of family richness and biased low at

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

error bars around a point
All
Is there an R command to produce error bars around
a plotted point. Crawley's book uses the command
error.bar() but my version of R rejects it. Must be an
S+ command(?).
