reshape
I'd like to convert a data.frame from (long format):
gen maxh resp
1 12.3 y
. . .

where resp is a factor with levels "y" and "n"
to the wide format:
gen maxh.y maxh.n

I've done it as follows:
maxh.y <- split(maxh, resp)$y

[cfe-dev] GN build roundtable summary; adding GN build files to the repo
Any easy way to do this as some kind of overlay, so they GN files wouldn't
live in the LLVM repository, but in a separate one?
(this might avoid some of the community discussion - though would perhaps
still likely have the issue I see as most significant: With a sufficient
number of developers using GN, the rate of build breaks due to those
developers missing CMake file updates might rise to

[cfe-dev] GN build roundtable summary; adding GN build files to the repo
The value in having them somewhere in-tree is that it's easier for people
collaborate on these files, and it's way lower setup overhead if someone
wants to try it out. If people prefer llvm/util over llvm/experimental,
that's fine with me.
There would only be a single directory that will contain build files for
all of llvm, clang, lld, etc. The build files would be in

Ordering problem
I have an ordering and factor problem to which there must be a simple
solution! The version is R 2.0.1 (2004-11-15) on A Linux platform.
A data frame H is read in from a .csv file using read.csv with as.is=TRUE.
Another data frame HN is constructed from data and I want to compare two
columns both named ss of the (sorted) data frames that are the same
length.
The problem is that HN$ss is

[cfe-dev] GN build roundtable summary; adding GN build files to the repo
Awesome. I'm happy with moving the .rst file into that directory and not
have it on the public website. I'll try to make a patch that lands enough
scaffolding to build `not` in the next few days, and then I'll land the
other build files I have through the regular build process after that.
Unless someone feels strongly, I'll go with Justin's suggestion of

[cfe-dev] GN build roundtable summary; adding GN build files to the repo
If I read this correctly, there isn't much opposition to landing the gn
files as long as it's very clear that regular devs aren't supposed to
update them and that it's clear that they're experimental
The main concerns I've heard so far:
- Having two build systems is confusing. I can see this, but I think

avoiding a loop?
Hi All:
I feel like there must be a slick R-native no-loop way to get the counts
for the entries in a factor, but I'm unable to see how. Right now I'm
doing this:
hn.ent<-data.frame(rep(0,length(levels(hnf))), row.names=levels(hnf))
colnames(hn.ent)<-c("count")
for (lev in levels(hnf)) {
hn.ent[lev,"count"] <- sum(lev == hnf)
}

Need help on identifying a patch which fixed lld on linux platform
Thanks for the info Rui.
Transitioning from llvm 5.0 to llvm 7.0 will take some time due to the
nature/process of the production environment. Is it ok to use lld 7.0 with

plot of computed vector
gReetings:
I apologize for the non-programming language. I found what seems to be a
strange behavior of plot(). The code follows:
#_____________________________
N=3030; gn=.04; tn=1:100
n=N/(1+(N-1)*exp(-gn*tn))
N=n*(1-exp(-gn*tn))/(1-n*exp(-gn*tn))
plot(N) #strange plot
N
N=rep(3030, 100)
plot(N) #behaves as expected

Speex mem
Hi,
I need to get an overview over the memory/speed requirements for speex.
We want to investigate whether we can implement on a target processor
with limited resources.
The target processor is a 16 bit fixed pint DSP with a single ALU and
MAC. It runs at 60 MHz and has a total of 16 Kbytes RAM from which other
processing also will eat.
What we would like to implement is a speex encoder and
