[R] Exporting the formula for a LOESS fit

2009-09-10 Thread jrflanders
I'm at my wit's end, and have searched all of my sources. I need to generate a relatively large number of individual LOESS fits each month of data (I have about 16 months of data). Fitting the polynomial is not my problem, figuring out what the formula that describes that polynomial is. apologies

[R] Why don't formulas that work for lm() work for plotmeans?

2009-09-18 Thread jrflanders
I know that simple line plots showing a point representing the mean + an error bar are difficult in R, but I am clearly missing something. I simply want to show how a the mean and 95% CI of a chemical concentration (y) vary over space (x) under four temperature regimes (T; a categorical factor).

[R] xyplot (Lattice): Group order in display

2010-09-01 Thread jrflanders
Dear R users, I would like one of my groups in xyplot to appear to lie 'behind' the other groups. I have searched for help and find many, many topics about panel order (e.g., "as.table"), but that is not what I need. What is odd is that the group that I want to appear 'behind' the others (PROFIL

For some reason the factor.levels labels just aren't printing. It just says "EVENT." strip works just fine. On Wed, Sep 1, 2010 at 12:45 PM, Deepayan Sarkar [via R] < ml-node+2413989-1836328520-57...@n4.nabble.com > wrote: > On Wed, Sep 1, 2010 at 9:00 AM, jrflanders <[h

Yes, event was coded as an integer. As I said, always something simple. I'm learning. By the way, I cited lattice in my recent paper in Applied Geochemistry. Thank you for your work. On Sep 7, 2010 1:32am, "Deepayan Sarkar [via R]" wrote: > On Thu, Sep 2, 2010 at 1
