As example: var_filename = as.name("aaa") jpeg("var_filename.jpg") plot() dev.off() It would be very useful in order to avoid to change manually many strings. I guess it is possible, but I did

Dear list, I have to compare two digital elevation models in raster format (geotiff). I then have to calculate the differences in altitude for each cell and make some statistics (basic as mean, median, std, range but also more "advanced" as RMSE) on that. I do not know very much how to proceed: 1) is it possible to import the geotiff in R? If so with which package? if not which is the

Dear list, I just tried to use the function cluster.stat in the package fpc. I just have a couple of questions about the syntax: cluster.stats(d,clustering,alt.clustering=NULL, silhouette=TRUE,G2=FALSE,G3=FALSE) 1) the distance object (d) is an object obtained by the function dist() on my own original matrix? 2) clustering is the clusters vector as result of one of the many clustering methods?

I succeeded partly using the function method. However in my script I call the sink() function in order to output the results to a .txt file. When using the function the

Hi there, I have just started using the MASS package in R to run M-estimator robust regressions. The final output appears to only give coefficients, degrees of freedom and t-stats. Does anyone know why R doesn't compute R or R-squared and why doesn't give you any other indices of goodness of fit? Does anyone know how to compute these in R?

Dear list, I have to draw a simple plot. On y axe some numerical values that correspond to various categories on axe x. The table I am reading looks like: cat Obj1 Obj2 Obj3 max 23 27 34 ave 21 25 32 min 19 23 30 In order to avoid that the first column is reordered alphabetically I used: (found here http://tolstoy.newcastle.edu.au/R/help/06/09/33808.html) a <- as.character(table$cat)
