Hi, I am using mtext instead of the ylab argument in some plots because i want to move it away from the numbers in the axis. However, the text in the X axis, for example: par(mar=c(5, 5.5, 4, 2)); plot(data, main="plot name", xlab= 'X axis', ylab="", font=2, cex.lab=1.5, font.lab=2, cex.main=1.8); mtext('Y axis', side=2, cex=1.5, line=4,

Dear subscribers, I have made a simulation using loops rather than apply, simply because the loop function seems more natural to me. However, the current simulation takes forever and I have decided - finally - to learn how to use apply, but - as many other people before me - I am having a hard time changing habits. My current problem is: My current code for the loop is: distances <-

...; or 'calibrate' functions from package "Design", and I also experimented with function 'sm.binomial.bootstrap' from package "sm". I tried also the function 'boot' from package "boot", though without success - in my case it randomly selected _columns_ from my data frame, while I wanted it to select _rows_. Though the main point here is the optimized LR equation. I would appreciate any help on how to extract the LR equation coefficients from any of these bootstrap functions, in the same form as given by 'glm' or 'lrm'. Many...
