Also why should that difference result in different behavior?

Also note that the functionality discussed could be regarded as a generalization of matrix multiplication where * and + are general functions and in this case we have * replaced by == and + replaced by &.

Hi, I am using RpgSQL to retrieve data from a PostgreSQL database wich is with encoding UTF8, and I have some Chinese character in one of the columns, unfortunately R can't show it correctly. > df <- dbGetQuery(con, "select * from test") > df a b 1 1 ????????\xa2 2 2 ???? EURO\xa1 I see the following option, do I need to change the encoding option to show

...back to you. Nevertheless, having a installer and a "portable" version is something pretty common (R Studio, Notepad++ and 7Zip pop to my mind now) and pretty helpful to deal with security restrictions, so I thought R had one, somewhere.

Thanks. I found this to be quite informative and a nice example of how useful R-Help can be as a resource for R users.

.... I cant execute exes. But I can unzip files. Thanks Gabor, I had that in mind, but can't execute the exe due to security restrictions. Geez, really, treating people who ask questions this way just makes you don't want to ask a single one.

Hi, I have a question for my simulation problem: I would like to generate a positive (or semi def positive) covariance matrix, non singular, in wich the spectral decomposition returns me the same values for all dimensions but differs only in eigenvectors. Ex. sigma [,1] [,2] [1,] 5.05 4.95 [2,] 4.95 5.05 > eigen(sigma) $values [1] 10.0 0.1 $vectors [,1]
