[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.

Group by in R
Hi,
I have the following table data:
f1, f2, f3, f4.
I want to compute the counts of unique combinations of f1-f4. In SQL I would
just write:
SELECT COUNT(*) FROM <table> GROUP BY f1, f2, ..,f4.
How to do this in R?
Thanks,
Nick

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:

Applyiing mode() or class() to each column of a data.frame XXXX
Hi everyone,
I am attempting to use the apply() function to obtain the mode and class of
each column in a data frame, however, I am encountering unexpected results.
I have the following example data:

rsync --delete problems
For some time I have been using rsync to backup data between different
machines and my NAS drive.
But within the last 2 days I have found out that rsync is not removing old
files from destination - directories renamed or removed from source.
In this example I want to sync files on my Debian Linux server to a NAS
drive. NAS drive is mounted using smbmount.

subsetting levels of a vector
Hi,
I need to subset different levels of vector in a dataset to create a new dataframe that contains only these. These observations are not numerical, so I can't use the subset() function (at least this is the response I get from R).
Suppose the dataframe looks like this:
ParticipID ERP Electrode
1 s1 0.0370 FP1
2 s2 35.0654 FP2

DUNDi .... Halfway
Well, I've been dicking around with DUNDi for about 4 hours now. I have two systems that I am trying to get to peer with each other. Queries are working one way, but not the other. The server, pbx1, that is refusing to deliver any queries and logs what's below to the console. Why??? I've checked all the config files more times than I can remember. The 'RFC' for DUNDi at

Glusterfs/CTDB/Samba file locking problem
Hi guys,
I try to set up two identical installed up to date CentOS6 machines with Glusterfs/CTDB/Samba .
I have set up Glusterfs and it works. I have set up CTDB from CentOS and it seems to work too.
Samba is AD integrated and works mainly.
The main problem is that file locking seem to not work between the machines at all. If two Win7 clients try to open an document

step.lm() fails to drop {many empty 2-way factor cells} (PR#3491)

This may not be a bug in the strictest sense, but at least
something for the wish list. Unfortunately I have no time

data.frame within a function (PR#9294) (cont'd)
This continues the message "data.frame within a function (PR#9294)" that
was posted on 2006/10/12. Duncan Murdoch kindly replied. I'm using the
current version R 2.4.0, but the same issue exists. Just copy and paste
the following code under R, and compare the output of f1() and f2() and
the output of f3() and f4(). Does anybody have any idea? Thanks.

Problem reading in table with extra spaces
I wrote with C and created a file that I can read into S+, but R chokes
because I've got multiple spaces between some variables and there is a
space at the start of each data line. This happens becuase C was
right-justifying the numbers as it printed them out. It looks like
this:

REML - quasipoisson
hi
I'm puzzled as to the relation between the REML score computed by gam and
the formula (4) on p.4 here:
http://opus.bath.ac.uk/22707/1/Wood_JRSSB_2011_73_1_3.pdf
I'm ok with this for poisson, or for quasipoisson when phi=1.
However, when phi differs from 1, I'm stuck.

help with checking out-of-range values in each column in data frame
Dear list,
I have following data, where I want to check if any value in each
column is out of range. For example, column "f1" can only take values
1-5, so if any values less than 1 or > 5 will be
defined as missing value (i.e. NA), column "f4" can only take values
of 1-3 and any values that are outside this interval will be
considered as missing values. The below

Plotting a segmented function
This might be a trivial question, but I would appreciate if anybody
could suggest an elegant way of plotting a function such as the
following (a simple distribution function):
F(x) = 0 if x<=0
=(x^2)/2 if 0<x<=1
=2x-((x^2)/2)-1 if 1<x<=2
=1 if x>2
This is just an example. In this case it is a continuous function. But
how to do it in general in an elegant way.
