as.xts convert all my numeric data to character
Hello, all... I've been playing with the TTR package and quantmod, and I'm
loading the Chicago Board of Exchange put/call ratio data via a simple
read.csv call...
CBOEtotal<-read.csv(file="
http://www.cboe.com/publish/ScheduledTask/MktData/datahouse/totalpc.csv
",skip=1)
this gives me a data frame with columns....

masking of objects between mtrace() and getYahooData()
I am using getYahooData from TTR to get daily data. When i do it standalone,
it is fine. It also works fine inside my code. However, when i run code
inside mtrace(), i always get the following error:
Error in xts(cbind(adj[[1]], adj[[2]]), index(obj)):
order.by requires an appropriate time-based object
After a lot of hand wringing, it looks to me that it happens because index
in xts masks

Fwd: Skipping names of temporary symbols increased size of ARM binaries.
CC llvm-dev
---------- Forwarded message ----------
Hello Duncan
The size of ARM binaries created by clang has increased after r236642.
Would you be able to find some time to look at my findings and share your
thoughts about the problem, please?
r236642 prevents emitting of temp label names into object files to save
memory. This is fine, the label names do not appear in the resulting
binaries.

abline(h=whatever) not working in candleChart() (in quantmod)?
Hello, all--
I am having some fun playing with the graphing in quantmod-- very nice! I am
writing a function to calculate (and hopefully plot) support and resistance
lines, but the usual plot call of "abline(h=value)" does not seem to work.
Here's my code:
require(quantmod)

[LLD] Is there any reason to add _GLOBAL_OFFSET_TABLE_ to .dynsym?
When LLD builds a shared library for x86_64 it puts
_GLOBAL_OFFSET_TABLE_ to the both .symtab and .dynsym and defines it
as a GLOBAL symbol. If later this shared library participates in
executable file linking and GNU BFD linked is used for that, this
linker shows an error:
/usr/bin/ld: a.out: hidden symbol `_GLOBAL_OFFSET_TABLE_' in
/usr/lib/x86_64-linux-gnu/crt1.o is referenced by DSO

Plot dies with memory not mapped (segfault) (PR#9785)

Version: 2.5.0 (2007-04-23)
OS: Solaris Nevada Build 55b
Submission from: (NULL) (65.101.229.198)
I find that running this script causes R to segfault reliably. However, running
just for one system at a time (modifying the for loop updating iter to run just
for a system at a time works). The system is a Sun W2100z with 12 GB of ram, and
R segfaults using only around 360 MB of

error with lme within a loop
Dear R users,
I want to conduct a small simulation study and I have to use the lme

Why my messages are filtered from the list?
Now I am getting confused. I see two postings from me in the archives:
https://stat.ethz.ch/pipermail/r-devel/2015-May/071205.html
https://stat.ethz.ch/pipermail/r-devel/2015-April/070982.html
Were these actually published to the list? If so - big apology.

[RFC] Aggreate load/store, proposed plan
It is pretty clear people need this. Let's get this moving.
I'll try to sum up the point that have been made and I'll try to address
them carefully.
1/ There is no good solution for large aggregates.
That is true. However, I don't think this is a reason to not address
smaller aggregates, as they appear to be needed. Realistically, the
proportion of aggregates that are very large

SMA and EMA in package TTR
Hi,
Just wondering for the SMA and EMA in package TTR, is it possible to me to
code it so that, say if I need to calculate SMA (x, n=100), when the sample
size is less than 100, it will give me the SMA (x, k) where k is the sample
size of the data? Right now it only gives me an invalid n error.
Thanks!
