updating a helper function in a R package
Hi list,
Sorry for the vague title, but here is the scenario.
I?m writing an R package, let?s say, ?pkg1?, which contains 3 functions: f1, f2, f3. f2 and f3 are helper functions for f1, i.e. f1 calls f2 which in turn calls f3.
f1 <- function(?) {
?.
f2()
?
}
f2 <- function(?){

f3(?)

}
f3 <- function(...){

Then, I wrote a new version of f3 and I want to

[LLVMdev] [NVPTX] llc -march=nvptx64 -mcpu=sm_20 generates invalid zero align for device function params
Hello,
FYI, this is a bug http://llvm.org/bugs/show_bug.cgi?id=13324
When compiling the following code for sm_20, func params are by some reason
given with .align 0, which is invalid. Problem does not occur if compiled
for sm_10.

Plotting 1 covariate, 3 factors
I'm interested in plotting a y with an x factor as the combination of 2
factors and colour with respect to a third, which the code below does with
interaction.plot(). However, this is because I redefine the x to be 1
factor. Is there a way of getting it to plot without redefining it, and
ideally to not join up the lines BETWEEN levels a and b, but just join those
between after and before for

How should I denormalise a data frame list of lists column?
Hi,
I have a data frame where one column is a list of lists. I would like to
subset the data frame based on membership of the lists in that column and be
able to 'denormalise' the data frame so that a row is duplicated for each of
its list elements. Example code follows:
# The data is read in in this form with the c2 list values in single strings
which I then split to give lists:

slow computation of mixed ANOVA using aov
Dear R-help list,
I am trying to do a mixed ANOVA on a 8960 x 5 dataframe. I have 3 factors
for which I want to test all main effects and interactions : f1 (40 levels),
f2 (7 levels), and f3 (4 levels). I also have a subject factor, subject, and
a dependent variable, dv.
Some more information about the factors:
f2 is a between-subject factor. That is, for each level of f2 there are 8

Counting observations of a combined factor
#I have a dataset with two factor. I want to combine those factors into
a single factor and count the number of data values for each new factor.
The following gives a comparable dataframe:

b <- rep(c("c", "d"), c(6,6))
df <- data.frame(f1=a, f2=b, d=rnorm(12))

right assignment ("->") and functions

Error: couldn't find function "f3"
Why does right assignment "->" work in the first but not the second

Arguments passing through dot-dot-dot lose ability to check for missing()?
Hi R-devel. Is the following behavior in g1() and h1() expected? It seems
to make "..." arguments work slightly differently from named arguments.

#for example, "z" can be missing in f3 even if
#that argument did have a name ("y") in f2

sem is not "taking" the model
A strange problem with sem:
I downloaded the sem library and then, I specified my simple measurement model (below). I highlighted it and ran it. It ran, but it did NOT tell me "22 lines read". And nothing works after that - it looks like it runs, but it does not produce anything...
Did I make a mistake somewhere in the model? (notice, TIME has only 1 indicator - t1, and I fixed t1's
