Hi,
I am brand new to R and therefore apologize if my questions sound stupid or if I don't use the right words. I would like to perform a correspondence analysis with the ca() function of Labdsv, but here is what happens when I try: caherbpour<-ca(herbpour) Erreur : impossible de trouver la fonction "ca" I checked that labdsv is installed: I have the 1.0-1 version. From what I can see, the other labdsv functions are OK, since I can find files such as const.R, importance.R or pca.R (which are other functions of the labdsv package) in the R library (but NOT ca.R or any other type of file with the name "ca" in it). I also tried to launch some of these other functions. I receive error messages because I don't know yet how to use them (ie. what arguments to enter), but they are at least found by R. Is it possible the labdsv package I have is not complete (although I installed it via Package Installer -> Get List -> CRAN binaries) and that the ca function is missing ? I saw one can also perform CA analyses with the cca function of the vegan package. Would it be a better solution ? are there differences between the ca function of labdsv and the cca one of vegan ? In case this can help, my operating system is OS 10.3.9 and the version of R is 1.12 (v1622) Thank you in advance for your help!
