Hi: My head is spinning with this latex doc so hopefully after I align my tables to the left of the page my headache are going to be over.

Not sure if \begin{landscape} has something to do with it or is just me. I? hope someone

Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

Hello all: Is there a way to detect in R if a dataset is normally distributed or skewed without graphically seeing it? The reason I want to be able to do this is because I have developed and application with Visual Basic where Word,Access and Excel "talk" to each other and I want to integrate R to this application to estimate confidence intervals on fish sizes (mm). I basically want to

Hello: I have 5 years of weekly passage data and want to predict fish passage for the following year. I don't have a model to use to predict data for the sixth year. Can I somehow still predict based on these five years? I just want to see on the graph what the predicted year would look like and how those?new values are generated.
