Hello everybody, i'm having some trouble performing correspondence analysis with R for Mac OS X. Does anyone know about some useful package? And also, if i had found coordinates of points representing row and column profiles, how do i put them in a single figure with labels identifying each one of them? This thing is getting me almost crazy... Thank you in advance for answering, bye

Hi everybody, while performing ks.test for a standard exponential distribution on samples of dimension 2500, generated everytime as new, i had this strange behaviour: >data<-rexp(2500,0.4) >ks.test(data,"pexp",0.4) One-sample Kolmogorov-Smirnov test data: data D = 0.0147, p-value = 0.6549 alternative hypothesis: two.sided >data<-rexp(2500,0.4)

Hello to everybody, I'd like to submit a problem I'm dealing with, and I can't get an answer to by myself. I have to test if my data come from a specific probability distribution, of which I know the analytic form both of the p.d.f. and the c.d.f. Namely, it is the hypoexponential distribution, sum of two exponentials with different parameters. Is there any way I can manage the

Hi everybody, i'm dealing with some percentage tables, of which i should test rowwise if the entries are sgnificantly equal or not. Namely, on row 1, test H0: element 1= element2, H0: element 1= element3...H0: element 2= element3...H0: element n-1= element n. The same on the other rows. Anybody knows how this can be done in quick way? I don't have large matrices, but it seems quite

Hi all, thank you for your answers; i've tried both cca from vegan library, and dudi.coa from ade4 library; one last question: my deal is mainly with contingency tables, like the one i'm posting here acciaieria<-c(.41,.02,.44,.04,.09) laminatoio<-c(.34,.28,.26,.01,.11) fonderia<-c(.48,.05,.34,.08,.05) leghe<-c(.45,.19,.25,.03,.08)

Hello, I'm trying to export Samba shares that access a PVFS2 (http://www.pvfs.org/pvfs2)-mounted partition. PVFS2 is a parallel, distributed file system for Linux clusters. PVFS2 gets mounted like any other partition and it offers non-POSIX file semantics similar to NFS. We can use standard shell commands (mv, ls, cp, etc.) to read and write files on the PVFS2 file system without any

Hi all, I'm seeing doubled quotas on Windows 7 when connecting to Samba. By doubled, I mean that if I set a 1GB group quota on Linux, I see a 2GB quota on Windows 7. The quotas seem correct with Samba 3.6.19 running on a Linux 2.6.32 kernel on Mandriva; they are incorrect with Samba 3.6.22 on a Linux 3.12 kernel on Ubuntu. What could be wrong? In more detail, I'm testing on both a
