[R] Mysterious Eclipse / StatET error messages

All, I'm not sure when this started, but I've noticed that just about any time I add to an R script in Eclipse, I get a warning in Eclipse's error log that looks like the following: Unhandled/Unknown code of R AST node: Code: 0x100 Node: <- (195, 70) Line 4 at offset 195 (can be wro

Re: [R] monotonic factors

One approach would be to code dummy variables for your factor levels, have d1 equal to 0 for 'low' and 1 for 'med' and 'high', then have d2 equal to 1 for 'high' and 0 otherwise. For linear regression there are functions that will fit a model with all non-negative coefficients, but I don't know

Re: [R] Chi-Square test and survey results

The chisq.test function is expecting a contingency table, basically one column should have the count of respondents and the other column should have the count of non-respondents (yours looks like it is the total instead of the non-respondents), so your data is wrong to begin with. A significant

Re: [R] Applying function to only numeric variable (plyr package?)

Hi: One approach to this problem in plyr is to use the recently developed mutate() function rather than ddply(). mutate() is a somewhat faster version of transform(); when used as a standalone function, it doesn't take a grouping variable as an argument. For this example, one could use mutate(df,

Just a comment on the lack of a direct R API for non-IBrokers brokerages: of course its possible to put something together using rJava or a direct C interface, but it's not the smoothest thing if you've never delved into the R internals and it's not quite the fastest thing in the world if you are d
