[R] Problem with RGenoud
I've been using RGenoud for a while and it worked smoothly so far. However I came across a strange problem lately (for me at least...). It fails after the first individual and I get the following error message when I set MemoryMatrix = FALSE : Error in genoud(fn, nvars = 8, max = TRUE, pop.size = 10, : REAL() can only be applied to a 'numeric', not a 'character' when I set MemoryMatrix = TRUE, it fails after it runs the total number of individuals in the 1st generation: Error in population[eval.indx, nvars + 2] = 0 : incorrect number of subscripts on matrix It sounds like it struggles to write results to an outside source (not sure this is the appropriate language). I ran many RGenoud based optimization before based the same set up and I never came across that issue before. I checked the fn function and it works OK outside RGenoud. I'm using R 2.10.1 with under Windows Vista and RGenoud version 5.6-6 Any help appreciated Thanks -- View this message in context: http://n4.nabble.com/Problem-with-RGenoud-tp2014722p2014722.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] problem with chartSeries
Hi All,
I came across some trouble with this function when trying to plot intraday
data. I can't manage to plot candelsticks I get a line instead and I don't
understand why. I put below data sample and code.

The below code gives me a line chart instead of candlestick. I can't figure
out why???
chartSeries(x,
TA = NULL,
theme = chartTheme('black'),
up.col = 'white',
dn.col = 'tomato',
type = "candlesticks",
name = "EUR",
minor.ticks=FALSE)
the x object seems to have the right attributes (see below)
> class(x)
[1] "xts" "zoo"
> head(index(x))
[1] "2010-10-27 08:59:59 CEST" "2010-10-27 09:05:00 CEST" "2010-10-27
09:09:59 CEST" "2010-10-27 09:15:00 CEST"
[5] "2010-10-27 09:19:59 CEST" "2010-10-27 09:25:00 CEST" "2010-10-27

[9] "2010-10-27 09:40:00 CEST" "2010-10-27 09:44:59 CEST"
Did I miss something obvious?
Any help appreciated Thanks

[R] prb with data.table
R.2.11.1 on Windows 7
When running data.table examples.
> DT = data.table(x=rep(c("a","b","c"),each=3), y=c(1,3,6), v=1:9)
> setkey(DT,x)
> DT["a"]
I get the following error message
Erreur dans seq.default(to = xlen, length = n) :
length must be non-negative number
When running the test.data.table(), pretty much all the tests fail (see
below)
Test 8 Error in seq.default(to = xlen, length = n) :
length must be non-negative number
Test 9 Error in seq.default(to = xlen, length = n) :
length must be non-negative number
.
Any help appreciated
