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

Dear help, suppose I have this array and want to compute sd aross rows and columns. p <- array(c(1:5, rep(NA, times = 3)), dim = c(5, 5, 3)) apply(p, 1:2, sd) fails because sd requires at least 2 numbers to compute sd apply(p, 1:2, sd, na.rm = TRUE) fails for the same reason I crafted my own function that does what I want sd_fun <- function(i){ if(sum(!is.na(i))==0){ temp.sd <- NA

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
