[R] lattice plots - variables in columns

I an using xyplot in lattice. I have data in a dataframe. Some columns contains data, each from a different group. Is there a direct way to specify a range of column names as a grouping variables? Currently, I am stacking the data and creating a column with names. Thanks, Matt -- Matt

[R] lower case Greek letters

! 7 alpha - omega Capital greek letters so I suspect it may have something to do with my system, but I am at a loss as to what. Any suggestions as to what to check would be appreciated. I am running R version 2.1.0 on Debian Linux - version sarge. Thanks, Matt -- Matt Pocernich R

[R] lattice variable by page

Hi, Using lattice's xyplot, is it possible to specify a variable to group plots by page. For example, if I have xyplot(y~x|A*B*C) could I get a page created for each unique value in variable C ? I am hoping to avoid having pages with the same strip above each plot on a page. Thanks, M

[R] lattice.device in loop

ke this to produce a large, appended file made from different large datasets. This doesn't work either. trellis.device(postscript, file = "/d1/pocernic/test.ps", onefile = TRUE) for(i in 1:5){ xyplot(y~x, data = dat) } dev.off() Any thoughts would be welcomed. Matt Pocernich N

Re: [R] Convert numeric value to POSIXct

I found my error. I was using cbind to connect a vector of POSIXct values and numeric values. Doing this caused the POSIXct format of the date vector to be lost. By correctly connecting them with data.frame, this was not a problem. Thanks, Matt Pocernich NCAR - Research Applications Program
