I compile these two lines in llc @tst1 = internal global [4 x i8] zeroinitializer; @tst2 = internal global [4 x i8] [i8 0, i8 1, i8 2, i8 3]; @tst1 is emited via MCStreamer::EmitCommonSymbol while the other is emited via MCStreamer::EmitLabel followed by MCStreamer::EmitBytes from what I can tell, only symbols with common linkage should me emitted by MCStreamer::EmitCommonSymbol, is this the

Function to Sort and test AIC for mixed model lme?
Hi List I'm running a series of mixed models using lme, and I wonder if there is a way to sort them by AIC prior to testing using anova (lme1,lme2,lme3,....lme7) other than by hand. My current output looks like this. anova (lme.T97NULL.ml,lme.T97FULL.ml,lme.T97NOINT.ml,lme.T972way.ml,lme.T97fc. ml, lme.T97ns.ml, lme.T97min.ml) Model df AIC BIC logLik

Speedups with Ra and jit
The topic of Ra and jit has come up on this list recently (see http://www.milbo.users.sonic.net/ra/index.html) so I thought people might be interested in this little demo. For it I used my machine, a 3-year old laptop with 2Gb memory running Windows XP, and the good old convolution example, the same one as used on the web page, (though the code on the web page has a slight glitch in it). This

grDevices::convertColor XYZ space is it really xyY?
grDevices::convertColor has arguments 'from' and 'to' which can take on value 'XYZ'. Can someone confirm that 'XYZ' is the same as the CIE chromaticity coordinates that are also sometimes refered to as 'xyY' in the literature? Or are these the CIE tristimulus values? It looks to me like the first case is true, but I would appreciate hearing from one of

Multiple plots in a single page and stripplot()
I want to make a 2x2 plot on a single page, using stripplot() and boxplot(). I tried the following two alternatives with mfrow() and layout(), but none of them worked. library(lattice) par(mfrow=c(2,2)) boxplot(X1 ~ Y, data=tst1, horizontal=T, las=1) boxplot(X2 ~ Y, data=tst1, horizontal=T, las=1) stripplot(Y ~ X1, data=tst1) stripplot(Y ~ X2, data=tst1) par(mfrow=c(1,1)) nf <-

Hmisc summarize() with level "" in by variable
I was using summarize() in a data set in which one of the levels of the by variable was "". The summary statistic was consistently off by one level and the "" level was not in the output data frame. I tried to report it as a bug, but I could not log into the Hmisc bug reporting website to do so. I searched for this in the email archives. If it's there, I failed to find

Calling function in DLL using .C
I cannot understand why a function appears to be available to R (is.loaded('planckwR') returns TRUE) but the call with .C results in an error message: C symbol name 'planckwR' not in DLL for package <path to DLL file here> This is what I do: Loading a homebrewed DLL, compiled with MS VS97. The functions are all void, the C calling sequence is used and all arguments

Density estimation when an end may not go to zero?
All the density estimators I've found in R seem to force the ends to go to zero. What can we do if we don't believe that, e.g., with something that might be a uniform distribution or a truncated normal with only observations above mu+sigma observed? The closest I could come to this was to artificially extend the numbers beyond the range, thereby forcing the density estimator

Memory issue
Reading a flat text file 138 Mbyte large into R with a combination of scan (to get the header) and read.table. After conversion of text time stamps to POSIXct and conversion of integer codes to factors I convert everything into one data frame and release the old structures containing the data by using rm(). Strangely, the rm() does not appear to reduce the used memory. I checked using

round() seems inconsistent when rounding 5s
It may be my lack of unerstanding, but round() seems to me to give inconsistent results when rounding 5s as in the following examples? > round(1.45, 1) [1] 1.4 # OK > round(2.45, 1) [1] 2.5 # shouldn't this be 2.4? > round(1.05, 1) [1] 1.1 # 1.0 ? and signif(): > signif(2.445, 3) [1] 2.44 # OK > signif(3.445, 3) [1]
