...gularities)"? What does this mean? I'm guessing that something to do with my SST data is causing a "singularity" but I don't know where to go from there? Have inspected various R discussions on this, but I haven't found the information I need.

Hello- I have been trying to install SciView under Windows Vista (Home Premium version, 32 bit OS, Intel Core Duo 2.13GHz, 2Gig RAM). I am getting an error, apparently related to the R2HTML package (version 1.54) as you will see in the R information below my signature. I have tried to email directly to support@sciviews.org for support but have had my message returned as undeliverable. Your help

I've a set of data to run a GLM on and am having trouble defining the categorical variables. For example, one of my variables is Year (ie. 1998, 1999). How do I define those years as factors/categorical variables? Cheers, Tim [[alternative HTML version deleted]]

Hello all- I would like to orient my polar.plot (from package plotrix) so that the circular scale runs clockwise and the origin (ie. 0 degrees) starts at the top of the plot. The defaults of running the scale counter-clockwise and beginning with 90 degrees at the top of the graph seems counter-intuitive to me. I'm using R 2.5.0, and plotrix version 2.2-4. Many thanks, Tim

Hi- I have two data frames for which I wish to conditionally subtract the values of one dataframe from the other. I want to subtract df1$x from df2$x when their id is equal and the absolute value of difference between the dates is 12 hours or less. If there is no match of equal id's and dates less than 12 hours apart I want it to return "NA". Note that df1 has missing values in x
