Hi all, I need a little help with flow control in R. What I'd like to do is to advance a for loop by changing its counter. However, what seems obvious to me does not yield the proper results. An example of my problem is for (i in seq(1, some_number, some_increment)){ <some stuff> if (some_condition == T) i <- i + 2; #want to advance the loop by 2 } Whenever the counter goes

hi, guys, as per subject. I've been working hard (searching hard, trying hard, googling hard) at trying to find a solution to the abovementioned problem, but nothing. I have several non-empty modules, all of which have files inside - NON-empty modules - but i have always failed to be able to rsync. Why? This is the behaviour: ----------- # rsync -vvv localhost::a . opening tcp connection to

Hi there, as a student sociology, I'm starting to learn about SEM. The course I follow is based on LISREL, but I want to use the SEM-package on R parallel to it. Using LISREL, I found it to be very usable to be able to see the total direct and total indirect effects (standardized and unstandardized) in the output. Can I create these effects using R? I know how to calculate them

...deals with the question when one of the Y's is dichotomous. Rivers, Douglas and Quang H. Vuong. 1988. Limited Information Estimators and Exogeneity Tests for Simultaneous Probit Models. Journal of Econometrics 39: 347-366 Alvarez, R. Michael and Garrett Glasgow. 1999. Two-Stage Estimation of Nonrecursive Choice Models. Political Analysis. 8: 11:24. I have not found anybody who has estimated one of these models with R, however, and was hoping to get an example from someone. I would also like to know if there is likely to be a problem extending the estimation framework to two multi-category depende...

Does anyone know if it''s possible to do the following: Given the directory structure: /foo/bar /foo/bar/<bunch of stuff> Is it possible to set /foo/bar to, say 555, and all stuff below to 440 or the directory equivalent? Thanks, Trevor

Hi, I would like to use the sem package to perform a path analysis (no latent variables) with a mixture of 2 nominal exogenous, 1 continuous exogenous, and 4 continuous endogenous variables. I seek advice as to how to calculate the appropriate covariance matrix for use with the sem package. I have read through the polycor package, and am confused as to the use of "numeric" for

Today I found these comments in active record''s callbacks.rb file: # If the returning value of a before_validation callback can be evaluated to false, the process will be aborted and Base#save will return false. # If Base#save! is called it will raise a RecordNotSave error. # Nothing will be appended to the errors object. This caused me a lot of frustration earlier when I was

Hello everyone, I''m scraping a lot of sites for a project, and occasionally the scraped content will have "malformed UTF-8" characters. When the scraped content is processed (basically a database record is created), these characters often don''t appear as they''re supposed to. Normally, the following code works great: str.unpack("U*").collect {|s| (s
