Hi Giovanni, I think the ggplot2 package might help you out here. Do you want something like this?
library(ggplot2) data(mtcars) p <- ggplot(mtcars, aes(x=cyl, y=mpg)) p + stat_summary(fun.data = "mean_cl_boot", colour = "red", geom = "errorbar") + stat_summary(fun.data = "mean_cl_normal", colour = "blue", geom = "errorbar") ? See http://had.co.nz/ggplot2/stat_summary.html for details. -Ista On Fri, Apr 30, 2010 at 3:10 PM, Giovanni Azua <brave...@gmail.com> wrote: > Hello, > > I need to plot multiple confidence intervals for the same model parameter > e.g. so for the same value of the parameter in point x_1 I would like to see > four different confidence intervals so that I can compare the accuracy e.g. > boot basic vs normal vs my own vs classic lm CI etc. > > I like very very much the plotCI implemented here: > http://cran.r-project.org/web/packages/plotrix/index.html > > This is their example: > library(plotrix) > y <- runif(10) > err <- runif(10) > plotCI(x=1:10,y=y,uiw=err,liw=2*err,lwd=2,col="red",scol="blue",main="Add > colors to the points and error bars") > > but does not seem to support plotting multiple CIs but only one per point, is > there a similar library somewhere but having the possibility to plot multiple > CIs? > > I know there is the function "segment" but I like this one above more :) > > Thanks in advance, > Best regards, > Giovanni > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > -- Ista Zahn Graduate student University of Rochester Department of Clinical and Social Psychology http://yourpsyche.org ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
