Hi, I've been trying to get networking up and running on CentOS 7 in a VMWare (5.5) VM. From inside the machine (connected to console (GNOME desktop)) it looks like network is up.

** High Priority ** I have been trying to read an SPSS file into R using read.spss ("C:/Documents and Settings/Roderick Harrison/My Documents/RWORK/ihisdat.sav", use.value.labels = TRUE, to.data.frame = FALSE, max.value.labels = 500, trim.factor.names = FALSE, trim_values = TRUE, reencode = NA, use.missings = to.data.frame) Each time (at least 5 or 6 by now) I get the following

Hi, how can I attach variable labels originally read by read.spss() to the resulting variables? <pre> X <- read.spss('data.sav', use.value.labels = TRUE, to.data.frame = TRUE, trim.factor.names = TRUE, trim_values = TRUE, reencode = "UTF-8") names(X) <- tolower(names(X)) attach(X) </pre> Thank you S?ren

I have a dataframe from an On-Board Survey with weights ("expwgt") and variables for up to 8 used lines: VEH1 through VEH8. The lines are labeled "MT-..1" through "MT-902". I want to know how many transfers there are between MT-802 and MT-901. That is, when one of them is VEHx and the other is VEHx+1 or VEHx-1 E.g. {VEH1 = MT-802 AND VEH2 = MT-901 } plus {VEH2 =
