Hi, I am running a test to call an R script with in excel using VBA. My VBA code is shown bellow. The middle section of this mail also includes the content of my Rscript.

The problem I am seeing is that Rinterface.RRun instruction is interpreting the "\T"

Hi, We have some tight controls in our systems and I am having difficulty downloading/upgrading R packages.

The IT department needs to know the IP addresses. Thanks, Jorge Nieves [[alternative

Hi, I have a matrix of data values like the example bellow. I would like to extract a subset of the matrix for the values where the first column is negative. I am using the subset function. However, I am getting an error message that the conditional variable doe snot exist. For some reason, the subset operation only works if I transform the matrix to a data set using as.data.set().

I tried using the interpNA function, but I get an error message: > interpNA(holder, method = "linear") Error in approx(idx, x[idx], 1:n, method = method, f

My environment.rb contains config.time_zone = ''UTC'' If my understanding is correct, rails should assume time values coming from the database are UTC, and since config.time_zone is set to ''UTC'', it should not try to convert the times. Instead, rails is assuming that the db values are Eastern (my local zone) and is incorrectly adding four hours to convert to

Dear listers, I am trying to install RcppBDT_0.2.1 on my Windows machine using the function install.packages("./RcppBDT_0.2.1.tar.gz", repos=NULL, type="source"). Since this package is not like most of other packages in that it requires Rcpp and boost, I have installed Rcpp and boost first, and executed the install.packages function. Then, I got the following error message:

Hello, everyone I wonder if R has something similar to Excel function EDATE(start_date; months) which returns a serial number of the date that is the indicated number of months before of after the start date. Example (the second column EDATE(first_column; -6)): 01.01.1999 01.07.1998 02.02.1999 02.08.1998 06.03.1999 06.09.1998 I am working with a zoo object where the row names are dates and for

Hi, I would like to check which rows of 'types.prev' matrix pop up in 'types', following R in-built procedure. I tried 'match' function but it works in case of the one dimensional vectors.

Hi, I''m looking at using my table headings as links that reload the page and sort it by the field which was clicked on. As is common, if the list is already sorted by the field, it reverses the order. I''m now looking at a good DRY way to do this. I have 3 fields: name, date, race. I''m setting a parameter called so (for sort order) to either "up" or

Hello, I'm trying to write a function that returns the number of weekdays between a vector of start dates and a vector of end dates. Subtracting the 2 times the number of whole weeks is the easy part and works if the number of days is a multiple of 7. However, the number of weekend days in the tail is a little harder. It depends on both the start date of the tail and the number of days in

Estimada Gaby Nieves Si usted usa Rsutudio puede crear un archivo nuevo, le sugiero crear este, sin colocar nada, deje lo que escribe en forma automática, y finalmente ejecute desde el botón knit html. El fin es ver si nuevamente aparece el error. Si no hay error puede ser la codificación de texto (enconding...), incluso hay un problema al mover un archivo de un lugar a otro. Javier From:
