inner_perc_table?
Hello,
Does anyone on this list know what inner_perc_table is or where it is
typically found? I am trying to modify some source code and it is used
with the .C() function. When I try and run it, it states that
'inner_perc_table is not found'. It is only called in such a way and isn't
defined at any point in the previous code in which the function works.
Should this be in some other

How to call directly "dotTcl" C-function of the tcltk-package from the C-code of an external package?
I have a use case with tcltk-package where I need to repeatedly call Tcl/Tk functions
very quickly. For such purpose, the standard R-interface turned out to be too slow, and
better option has been to call package's C-function dotTcl directly from my own C-code.
Before R 4.4.0 it was possible to use getNativeSymbolInfo("dotTcl","tcltk")$address (or

bug report: nlme model-fitting crashes with R 3.4.0
lme() and gls() models from the nlme package are all crashing with R.3.4.0. Identical code ran correctly, without error in R 3.3.3 and earlier versions. The behavior is easily demonstrated using one of the examples form the lme() help file, along with two simple variants. I have commented the errors generated by these calls, as well as the lines of code generating them, in the code example below.

caret pls model statistics
Greetings,
I have been exploring the use of the caret package to conduct some plsda
modeling. Previously, I have come across methods that result in a R2 and
Q2 for the model. Using the 'iris' data set, I wanted to see if I could
accomplish this with the caret package. I use the following code:

Calling C implementations of rnorm and friends
Gabriel,
Thanks for that! I guess I really should have figured that one out sooner,
huh?
I understand why that wouldn't be CRAN-compliant. But then, what *is* the
proper way to do it? Is there any way I can call unexported functions from
another package and have it accepted by CRAN?
Also, if I instead re-write the random variable generating functions, do

count number of groups
Hello,
Simple question that I am stuck on and can't seem to find an answer in the
help files currently. I have a list which contains repeated ID's. I would
like to have R count the number of ID's. For example:
ID=c(1,1,1,1,2,2,2,2,3,3,3,3)
as.data.frame(ID)
Clearly, there are 3 groups. How would I have R give me the summary:

Merge matrices with different column names
A general question that I have been pursuing for some time but have set
aside. When finishing some analysis, I can have multiple matrices that
have specific column names. Ideally, I would like to combine these
separate matrices for a final output as a csv file.
A generic example:

reformatting some data

mirroring a loop device across an ssh connection
all,
I've been looking into a secure way of accessing a remote loopback
encrypted partition securely via openssh.
The basic idea I have currently is that a file/partition is connected to
/dev/loop0 on a remote server, which I have an ssh connection to. I
hold the key (for cryptsetup via dm_crypt) on the local client. I'd
like to mirror the loop device of the server on the client.

Better way of Grouping?
Hello R users,
This is more of a convenience question that I hope others might find useful
if there is a better answer. I work with large datasets that requires
multiple parsing stages for different analysis. For example, compare group
3 vs. group 4. A more complicated comparison would be time B in group 3 of
group L with B in group 4 of group L. I normally subset each group with

getNativeSymbolInfo("user_unif_rand") returns different results on windows and linux
Hi,
When loading a package that provides the user-supplied RNG hook
user_unif_rand, calling getNativeSymbolInfo("user_unif_rand") returns
informations about the loaded symbol.
I am using this to identify which package currently provides the RNG hook.
The results are the same on windows and linux if only one library
provides the hook.
If one loads a second package that provides this

Calling C implementations of rnorm and friends
Well,
For this particular use case why not just transform the parameters at the R
level and then call the existing function? Is there not a closed form
mapping?

Multivariate Power Test?
Generic question... I am familiar with generic power calculations in R,
however a lot of the data I primarily work with is multivariate. Is there
any package/function that you would recommend to conduct such power
analysis? Any recommendations would be appreciated.
Thank you for your time,

Calling C implementations of rnorm and friends
Hi all,
Looking at the body for the function rnorm, I see that the body of the
function is:
.Call(C_rnorm, n, mean, sd)
I want to implement functions that generate normal (and other) random
variables. Now, I understand that I can perfectly well just call the R
wrapper for these functions and that will be almost indistinguishable for
most purposes, but for whatever reason I wanted to try and

Request
I apologize if this is out of line or the incorrect venue to make my
request.
I have spent months, off and on, attempting to download a large iso file
through my Linux desktop to my Linux-based server. It was frustrating
and damn near impossible. I kept suffering failures when the file size
hit 2Gig. I asked around in several newsgroups, I believe this mailing

cut2 error
To R users,
I am trying to use cut2 function from the 'Hmisc' library. However, when I
try and run the function on the following variable, I get an error message
(displayed below). I suspect it is because of the NA but I have no idea
how to address the error. Many thanks to any insights.
