I have encountered the following problem: I need to extract from a list of lists equally named compenents who happen to be 'one row' data frames. a trivial example would be: a <- list(list( df = data.frame(A = 1, B = 2, C = 3)), list(df = data.frame(A = 4,B = 5,C = 6))) I want the extracted compenents to fill up a matrix or data frame row by row. the obvious thing to do seems: b <-...

I am getting ready to load a bunch of data into R. The data is all numeric, but some of the numbers are integer codes representing non-numeric semantics. What is the best way to "fix" the data frames so that these compenents are recognized as "factors" or "ordered", as appropriate? Can I "assign" to some attribute of the data frame component, like the "class" or "levels" to get the desired effect? Thanks! -- Russell Senior ``The two chiefs turned to each...

Hi everyone. I have a quick question regarding the look of my legend in my plot. As you can see in the next figure, I have 3 series. http://r.789695.n4.nabble.com/file/n3067466/legend.png However, I find rather difficult to differentiate the series 1 and 3 according to their line type (lty). I would like to know if it was possible to make the line type in the legend to appear more clearly.

Hi Folks, Just a quick message saying that, after much demand, I wrote a quick write-up for the RoR + XUL thing I did yesterday: http://www.zedshaw.com/blog/programming/ruby_xul.html It lays out the few simple things I did, has a bit of rant on an unrelated topic, and other stuff but it''s short still. On a related note, I''d like to thank "xal" on IRC for reminding

Is there any package that assists in saving and reconstituting glm and nls fits without bringing along the accompanying data? A quick search on CRAN didn't turn up anything. If not, how do other people deal with saving the coefficients of model fits? For example, I've run a glm fit that has 23 coefficents on data set that had 193,008 rows, by the time the fit was called. When I save

Hello, I can't find how to get de column name from a data.frame dollar reference. To make it simple, I'd like to obtain "Bar" from a "foo$Bar" notation. I've tried col.names(foo$Bar), names(foo$Bar) and so on without sucess. Regards Blaise [[alternative HTML version deleted]]
