Hi. I have a problem that I can't seem to find an optimal way of solving other than by doing things manually. I'm trying to subset a data frame by the number of observations that occurred at a given row but want to take into account the number of observations of preceding rows. Here's an example. I'm looking at intervals of data [10,20), [10, 30), ....., [10,120) which contain a

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hmm why, the guy at https://raymii.org/s/tutorials/SAMBA_Share_with_Active_Directory_Login_o n_Ubuntu_12.04.html does exactly this. Also the manpage e.g. for smb.conf describes the config for a connection to an AD. And after granting file rights to the share via setfacl -m g:domänen-admins:rwx /var/samba/test I can mkdir and granting rights to

My code is as follows: #include <iostream> #include <cmath> using namespace std; #define MATHLIB_STANDALONE 1 extern "C" { #include "R_ext/Applic.h" } typedef struct TT{ double ** tempX; double * tempY; int tempN; } TT, *MM; double fn(int N, double * beta, void * ex){ double total = 0; int i = 0,j = 0; double * betaFn = new double[N]; MM tmp = (MM)ex;

Naresh, I am not sure how you are creating your data.frame so it has no, I think, column names. There are two scenarios including one where it is not really a valid data.frame and one where it can be handled before any other use as shown below. If it cannot be used, you might need to modify how your SQL or the function you call creates it so it includes either names it chooses or that you supply.

I am teaching a graduate course on Statistical Computing this semester. A major part of the grade is determined by a project in which a student or small group of students produce, test, and document some software for statistics. I will encourage those students who are developing in S to package their software as an R package. I would welcome suggestions of possible projects, especially projects

Hi all! I know there are plenty of tutorials that show how to set up a rails-enabled web server but I have a somewhat more tricky question: is there any way I can add Rails to my current web hosting service without having access to the httpd.conf nor ssh / telnet? I can use cgi however. I''m really confused! Thanks in advance! n_n -- Posted via http://www.ruby-forum.com/.

Data.frame is returned by SQL query. It does have column names. In the function, I make small changes to some columns. Something like: Myquery <- ?SELECT date, price, stock FROM stocktab WHERE stock = ?ABC? AND date > ?2025-01-01?;? Prices <- dbGetQuery(con, myquery) SetDT(Prices) Prices[, date = as.Date(date)] R CMD check say ?no visible binding for global variable ?date?? Sent

This solution worked.

That is an interesting fix Duncan suggested and it sounds now like everything WORKED as intended in data.table except that any checker being used externally is not able to del with things that look like a variable but are actually not a variable currently visible except within a function that is doing deferred evaluation. In this case, it recognizes the raw unevaluated string as being the name of

I have written a function which returns an SQL query result as a data.frame. Each column of data.frame is a variable not explicitly defined. For every column name, R CMD check says ?no visible binding for global variable <name>. Status: 1 NOTE Is it possible to tell R CMD check that these variables are OK?
