search for: 20bars

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. library(ggplot2) 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)) +

Does anyone have any recommendations for producing dotplots with error bars? Are there packages available for this? I searched far and wide and cannot find a suitable option. I am trying to produce publication-quality figures for my thesis results. Dotplots (Cleveland dotplots) are a much better form of summarizing barchart-type data. It does not appear that any of the main plotting packages in r

I'm new to this and struggling away with ggplot. I need to plot some line graphs for about 4 series. I have the values to plot and also the value of the standard error of the value. Is it possible to plot the standard error bars when the value are already calculated as opposed to letting R do the analysis to calculate the SE bars? Any simple example would be most appreciated.
