[Rd] Merge (PR#9699)
Full_Name: Edward McNeil Version: 2.5.0 OS: Windows XP Submission from: (NULL) (203.170.234.5) This is a new bug introduced to R2.5.0. Scenario: If one of the data frames to merge contains two variables that have the same name, then the data in first variable (of the same name) is copied to the second variable in the resulting merged data frame. In R2.4.1, the second variable name is automatically renamed (in the resulting data frame) by adding ".1" to the end. R2.5.0 doesn't seem to do this anymore. __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
Re: [Rd] Merge (PR#9699)
Yes, it appears to have been resolved in R2.5.0pat, although the
counter-example provided *does* fail in R2.5.0.
A <- data.frame(x=1:3, y=4:6, y=7:9, check.names=FALSE)
B <- data.frame(x=1:3, a=3:1)
A
x y y
1 1 4 7
2 2 5 8
3 3 6 9
B
x a
1 1 3
2 2 2
3 3 1
merge(A, B)
x y y.1 a
1 1 4 4 3
2 2 5 5 2
3 3 6 6 1

[Rd] Adding a survival object to a data frame (PR#10510)
Full_Name: Edward McNeil Version: 2.6.1 OS: Windows Submission from: (NULL) (203.170.234.5) I want to show students how the survival object looks like in R. Reproducible example: library(MASS) data(Aids2) attach(Aids2) status <- status=="D" stime <- death-diag surv <- Surv(stime, status) D <- data.frame(stime, status, surv) head(D,20) stime status x..i.. 1176 TRUE 176 2 67 TRUE67 3432 TRUE 432 4 77 TRUE77 5275 TRUE 275 6373 TRUE 373 7389 TRUE 389 8 1027 TRUE 1027 9492 TRUE 492 10 434 TRUE 434 1116 TRUE16 12 308 TRUE 308 1392 TRUE92 14 265 TRUE 265 15 1052 FALSE 1052+ 16 132 TRUE 132 17 527 TRUE 527 18 581 FALSE 581+ 19 511 FALSE 511+ 20 151 TRUE 151 detach(Aids2) The 'surv' column is strangely labelled 'x..i..'. __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Re: [Rd] Sys.setlocale upsets windows graphics device (PR#8887)
Hi,
We tried it on 3 separate windows XP computers using version 2.3.0.
The original locale is set for Thailand on all 3.
So how do we fix it? Is there another patch?
And why does the crash not happen with earlier R versions (eg. 2.2.1) on the
same computer?

> Sys.getlocale()
[1]
"LC_COLLATE=Thai_Thailand.874;LC_CTYPE=Thai_Thailand.874;LC_MONETARY=Thai_Thailand.874;LC_NUMERIC=C;LC_TIME=Thai_Thailand.874"

Thanks
Edward
