Executing Command on Multiple R Objects
Hello Everyone -
I want to print a number of results from lme function objects out to a txt
file. How could I do this more efficiently than what you see here:
out2 <- capture.output(summary(mod2a))
out3 <- capture.output(summary(mod3))
out4 <- capture.output(summary(mod5))
out5 <- capture.output(summary(mod6))
out6 <- capture.output(summary(mod7))

Cubic Gradient Descent Package
R -
Does anyone know of a cubic gradient descent package? I found grad.desc()
but that only allows for a 2d function. I have 3 free parameters and thus
am looking for a 3d function.
Thank you,

Axis Breaks with ggplot2
R-help -
I'm trying to create axis breaks similar to this :
http://www.r-bloggers.com/wp-content/uploads/2010/08/bar-chart-natural-axis-split1.png
.
Is there a way to do this in R? Here's my code thus far:
structure(list(condition = structure(c(2L, 1L, 3L), .Label = c("con",
"exp", "unedit"), class = "factor"), trial.avg = c(4.04583333333333,

Aggregate Table Data into Cell Frequencies
R-help -
I have this set of aggregated tables (sample data below via dput()). And I
would like to have delayValue as the column variables with the "temp"
(temp1, temp2, temp3) values as the row variables. However I would like to
have the temp variables *aggregated into single rows* so that I have the
frequency ("Freq" | counts) of each time each "delayValue" occurs

lme Random Effects and Covariates
1. I'm attempting to test for Random Effects. I've grouped the data on
subject (grid) but want to use lme to build the model without subject as a
RE then add it and do anova between the 2 models. This is the result I get
and it appears it's adding Random Effects.
tmp.dat4 <- groupedData(Trials ~ 1 | grid, data = tmp.dat4)
mod2a <- lme(Trials ~ factor(group_id) + reversal,
