[R] Comparing slopes in two linear models

Hi everyone, I have a data frame (d), wich has the results of mosquitoes trapping in three different places. I suspect that one of these places (Local=='Palm') is biased by low numbers and will yield slower slopes in the variance-mean regression over the areas. I wonder if these slopes are diferen

[R] Spatstat - Several density plots using the same scale

Hi everyone, I am using the package "spatstat" for ploting kernel maps of my data. It is a marked point pattern, the result of mosquito surveillance in a area in a week. For each trap, the number of individuals captured is the mark of the point. > plot(density(X, weights=X$marks)) makes a nice k
