I need some help understanding how on of the example data sets is formatted in the basic R installation. If I load the Mona Loa CO2 data, with the command: > data(co2) I can view the data with: > co2 And the data are in the form of 11 rows labeled as years (1994-2004) and 12 columns labeled (Jan - Dec). This structure appears to be a dataframe, however, if I type the command

I have what I hope is a ridiculously simple question. I am trying to follow an example that uses the function win.graph(), but my machine does not recognize win.graph(). I am running R 2.8.0 on OS X. Is there some OS X specific function that replaces win.graph or am I missing some package? Thanks in advance

How does one control the size and type of data symbols in pairs()? I am trying to use the little dot (as in type=".") with absolutely no success. Here is the pairs call I am using: pairs(data.frame, panel=function(x,y) {points(x,y); lines(lowess(x,y))}) or even simpler: pairs(data.frame, panel=panel.smooth) Any hints would be much appreciated.

I have a set of modeled climate data recorded at irregular intervals. The format of the data is such that there are monthly measurements for the years 2000, 2020, 2050, 2080, etc. Therefore I have 12 regular records, a skip of some number of years, then 12 more monthly records, another skip, and so on.... I created a dataframe from .txt with the read.table() command. For starters I need

I'd like to have a couple of windows app working in linux without rebooting (visual basic and JMP). I downloaded codeweavers wine but I have a question about windows partition or no windows partition... My present system is not dual boot. So ideally I'd like to run wine without a "real" windows partition. However, I have heard that wine works better with a "real"
