Hi, I am using the densCols to draw a high volume scatter plot. Instead of using the default local density, I would like to take log of the local density and then map them to the colors. I could not figure out how to do that. For example: plot(x,y,col=densCols(x,y,"log")) ? Any help would be appreciated! Jiaxiu [[alternative HTML version deleted]]

I have just began to use R. I would like to know where I can find in R the equivalent of the LSMEANS of SAS when I realise a lm.. In the summary, there is the estimate but it's different of the LSMEANS. In advance, thank you.

I am trying to fit regression models type II with R, but it seems to me that most (all) of the linear model functions are for type I regressions. Does anyone knows whether type II regressions functions exist in R.

Hi I need to a function that automatically fits a regression to data, using the stepAIC. I've ran the code manually and it works fine. However, when I run the function on the same data, the following error occurs: Problem in regimp(fullsim = simt, fullsim1 = simt1,..: Length of (weights) (variable 4) is 4271 != length of others (4278) I got the function to output the length of the dataset

Hi , I just imported a large data set from notepad. I want to label the columns in R. I used 'import Dataset' to bring in my data set Now, I would like to label V1,V2,V3 etc??

Dear all! I have a data frame composed by 13 columns (year, and 12 months). I want to transform this data base in another like this year month values 1901 1 1901 2 1901 3 ..... 1901 12 1902 1 1902 2 .... 1902 12 Is there a possibility to succeed that in R? Thank you! best regards! CR -- --- Catalin-Constantin ROIBU Lecturer PhD, Forestry engineer Forestry Faculty of Suceava Str.
