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

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

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? - Mike -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

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: Timestep Energy Variance_of_the_Energy 0.0005 -14.876840
