Looking for the name of a certain kind of quantile plot
Hi,
While playing with quantile-quantile plots, I wrote up some code which
plots something strangely different. Here's the pseudocode:
testhist <- hist(sample_data)
refhist <- hist(rnorm(n, mean=0,sd=1)) # for some large-ish n
cumtest <- cumsum(testhist)
cumref <- cumsum(refhist)
plot(cumref,cumtest)
This produces a straight line of slope 1 for a sample with the same
parameters as the reference sample, and produces S-curves for samples
with diff...

Loop Through Columns to Remove Rows
Hello Venerable List,
I am trying to loop (I think) an operation through a list of columns in a
dataframe to remove set of #DIV/0! values. I am trying to do this like so:
#Data.frame
test <- read.csv("http://dl.dropbox.com/u/1574243/sample_data.csv",
header=TRUE, sep=",")
#This removes all the rows with #DIV/0! values in the mean column.
only.mean <- test[!test$mean=="#DIV/0!",]
#This removes the majority of #DIV/0! values as there is a large block of
these values that extends over every column.
#However, it...

[PATCH 2/2] x86/vdso: Add VCLOCK_HVCLOCK vDSO clock read method
...ypervisor, better to not reuse seqcount.
> Still concerned that the code is racy.
That's a different question and can only be answered by the hypervisor
folks. Dunno, whether they have barrier requirements. The seqcount stuff
relies on:
do {
seq = READ_ONCE(s->sequence);
smp_rmb();
sample_data();
smp_rmb();
} while (s->sequence != seq);
which pairs with the writer side:
s->sequence++;
smp_wmb();
update_data();
smp_wmb();
s->sequence++;
That's important if the stuff happens cross CPU. If the update happens on
the same CPU t...

[PATCH 2/2] x86/vdso: Add VCLOCK_HVCLOCK vDSO clock read method
Since sequence count algorithm is done by hypervisor, better to not reuse seqcount.
Still concerned that the code is racy.
