Help with ENFA in R
Dear Jonathan, To import the maps, have a look at the function readAsciiGrid from the package maptools. To import the points, read.csv or read.table (use your prefered way to import data in R). Con HTH, Cl?ment Calenge.

Hi Mathieu
Thank you again. You are really helping me. Please forgive some of my
questions because I am very knew to R and I have to teach this to myself.
AdehabitatHS is using a different method to read the raster files. So when I
input this code: var1<- import.asc("Data/bio_01.asc") I get the following
error - Error: could not find function "import.asc". This makes sense to me
because sp classes are used. I have read both the vignettes and used the
example code for the lynx data but I am still struggling to interpret what
the vignettes are saying and to use my own data. The code map <-
lynxjura$map seems to contain all the environmental data. I am not sure how
to use the sp package to get my 15 environmental variables into a similar
dataframe. The same goes for my csv files - do I still need to use read.csv
or should I rather use something like $locs.
Thank you again
Jonathan
