Hi Julia, The error you got is usually due to data that should be numeric (1, 2, 3, ...) actually being a factor data type. This often happens when R reads in a CSV file with the default option of converting character variables (A, B, C,...) to factors. So your first column after input may be a fac

Julia: 1. I appreciate your honesty. 2. What follows is just my opinion. Feel free to ignore. 3. I think you are in a near impossible situation. R is a computer language for statistics and data analysis: you need to know both the language and statistics to use it properly. You know neither. So

Hi I think your plots are not *quite* horizontally aligned (because of differences in the lengths of y-axis labels). Here is a slight modification that messes with the labels (but at least not manually) to get things exact ... valign_lattice <- function(x) { if (inherits(x, "trellis"))

Hello All, I’m Julia from Germany and I have a problem concerning the vegan package that I can’t solve on my own (after hours and hours spent searching for a solution). I was thrown into the topic of working with R by my professor and wasn’t really aware that this included working with higher s

The organization of your data is not clear from your description. You say you have species and samples and that the rows are the species, but the columns (which should be the samples) are "zonation + land use". I'm guessing that you mean the first column was zonation and land use and the remaini

Hi, The following encapsulates what I hoped for using Paul's method. The function accepts one or more trellis class objects and aligns them vertically. I think I have automated most of the manual fiddling. Depending upon your graphics device you may need to fiddle with the aspect of the leve

Dear R-Users, a new package, "pinbasic", is now available on CRAN. According to the DESCRIPTION: Utilities for fast and stable estimation of the probability of informed trading (PIN) in the model introduced by Easley et al. (2002) are implemented. Since the basic model developed by Easle
