...n grouped by the levels of a factor coloumn of the datframe. I'm using the function "tapply" but I see that if only a NA value is present the result is NA. There is an option to have the correct result or I must use an other function?

...bject "lda" there is $scaling a matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical. I'd like to have the value of the discriminant function not normalized.

...* The function dunnfa performs a factorial decomposition of the Mahalanobis distances in habitat selection studies. This method has been suggested by Prof. James Dunn as an alternative * A new bug tracking system has been set up for adehabitat thanks to the great work of Paolo Cavallini (Faunalia). It is available at: https://www.faunalia.it/animove/trac/ Any other project intended to manage, store, analyze animals movements can be added there, provided it is free and open source. * Note that my e-mail adress has changed.

...like to have the values of the single columns expressed like percentage of the sum of the coloumn. In this way all the bars are composed by the sum of the percentage of the values of a coloumn (with different colors) and all they have 100% value.

Hello, I'm tring to make a linear discriminant analysis eith lda (MASS). In the value of the resulting object is there information about the value of the centroids of the discriminated group for the discriminant functions? Thank you in advance for your help!

Dear all, I'm using the package adehabitat in R to import several .asc files (=matrix), and also create a kasc object (=dataframe) with all of them. The main idea is to use this kasc object to map the predicted values of climate-matching model for an overall area. However, I don't know how to proceed: Do I have to project the model (already stored in R) onto the kasc object directly, or

Hi all, I have a little problem selecting some rows from a data.frame. I'd like to select the rows where a determinated column take a partivolar value.
