Full_Name: Barry Rowlingson Version: 1.6.0 OS: RH8 i386 Submission from: (NULL) (148.88.136.205) Strange things happen if I premultiply a difftime() object with a number. Example: > d1 <- difftime(Sys.time(),Sys.time()) > d2 <- 1 * difftime(Sys.time(),Sys.time()) > d3 <- difftime(Sys.time(),Sys.time()) * 1 > d1 Time difference of 0 secs - thats fine > d2 [1] 0

I see some value in Duncan?s proposal to implement this as an extra package instead of a change to base R, if only to see if the idea has legs. I?m minded to do so myself using your suggestion, but is there a particular reason why you recommend using the remotes package instead of devtools? The latter seems to have the same functions I would need, and I believe it is more widely installed that

Barry, Would you mind providing the necessary patch for this behavior?

Soon on CRAN a new version of package gstat will emerge, which has a few minor changes and possible incompatibilities w.r.t. the previous version(s). The new gstat (0.9-23) now: + depends on sp, and uses internally with Spatial* classes from sp if data are provided in the old-fashoned way (as data.frame) + has a vignette to get you started with the classes in sp + defines krige as a generic;

Source versions would only have been available with a nondisclosure agreement, and relatively few copies would have been distributed in source. There was a small but valuable "beta test" network, mainly university

Dear Barry, In general, I believe users are already accustomed with the classical arrows "->" and "<-" which are used as such in quoted expressions. But I agree that "-.>" is a very neat trick, thanks a lot. A small dot, what a difference.

Would you care to share how your package installs its own dependencies? I assume this is done during the call to `main()`? (Last time I checked, R CMD INSTALL would not install a package's dependencies...)

Hej hej, is there a way to extend the SpatialPointsDataFrame data slot?This is the structure of an object of it:> str(coord) Formal class 'SpatialPointsDataFrame' [package "sp"] with 5 slots ..@ data :'data.frame': 214 obs. of 2 variables: .. ..$ location.long: num [1:214] -79.8 -79.8 -79.8 -79.8 -79.8 ... .. ..$ location.lat : num [1:214] 9.16 9.16 9.16

ear ALL, The last part of my thesis analysis is the cross validation. Right now I am having difficulty using the cross validation of gstat. Below are my commands with the tsport_ace as the variable: nfold <- 3 part <- sample(1:nfold, 69, replace = TRUE) sel <- (part != 1) m.model <- x2[sel, ] m.valid <- x2[-sel, ] t<- fit.variogram(v,vgm(0.0437, "Exp", 26, 0)) cv69

Maybe someone has already suggested this, but if your functions accepted strings you could use sub or gsub to replace the -> with a symbol that parsed at the same precedence as <-, say <<-. Then parse it and deal with it. When it is time to display the parsed and perhaps manipulated formulae to the user, deparse it and do the reverse replacement. > encode <-

Hi Peter, The ssconvert tool (part of gnumeric) is very good at converting spreadsheets to csv-files. There is a wrapper in the "gnumeric" package on cran.
