...ing the export file from solaris box and then importing to R with read.xport, this gives rational numbers etc.) Trying to do this on an IBM Power p655 running linux, reading the same sas export file as used on MAC, in this case the results are not rational. Many of the numbers are interpreted as INF etc. Is it possible that the SOLARIS to Linux is causing this problem?

Hi, I noticed a minor flaw in integrate() from package stats: Taking up arguments lower and upper from integrate(), if (lower == Inf) && (upper == Inf) or if (lower == -Inf) && (upper == -Inf) integrate() calculates the value for (lower==-Inf) && (upper==Inf). Rather, it should return 0. Quick fix: ### old code ### ### [snip] else { if (is.na(lower) || is.na(upper))...

Hi, I think I've discovered a bug in base R. Basically, when using 'Inf' as as 'Date', is is visually displayed as 'NA', but R still treats it as 'Inf'. So it is very confusing to work with, and can easily lead to errors: # Visually displays as NA > as.Date(Inf, origin="2018-01-01") [1] NA # Visually displays as NA > st...

Hi Gabriel, The point is that it *visually* displays as NA, but is.na() still responds as FALSE. When I (and I am sure many people) see an NA, we then use is.na(). If we see Inf displayed, we then use is.infinite(). With as.Date() this breaks down. I'm not arguing that as.Date(Inf) should be coerced to NA. I'm arguing that as.Date(Inf) should be *visually* displayed as Inf (i.e. the truth!). I doubt this would break any existing code, because as.Date(Inf) acts...

Hi If I have a <- Inf + 1i then Re(a) is Inf, and Im(a) is 1, as expected. But if b <- 1 + Inf * 1i, then Im(b) = Inf , as expected, but Re(b) = NaN, which I didn't expect. Why this asymmetry?

...extend the available (fake) virtio-win drivers: - Patch 2 adds all of the drivers from the virtio-win RPM. - Patch 3 adds all of the drivers from the virtio-win ISO (which are different from the virtio-win RPM, for various reasons that don't make sense). - Patch 4 adds bits of the *.inf files, which will allow us to do proper driver discovery in future.

Hi, I am trying to produce an xyplot with a regression line. The data should be represented as log/log but when I fit the lmline I receive an error message - the plot is fine without the log transformation, but the then the plot is meaningless. I know it must be something simple, but I just can't see it. Hope someone can help... Thanks. xyplot(log(Pk)~log(k),data=rwpk,cex=1,

Hi Sebastian, It boils down to this: The previous heuristic solver could return infinite cost solutions in some rare cases (despite finite-cost solutions existing). The new solver is still heuristic, but it should always return a finite cost solution if one exists. It does this by avoiding early reduction of infinite spill cost nodes via R1 or R2. To illustrate why the early redu...
