no convergence using lme
...re was anything else in the control
values I should try changing.
Below are the defaults..
lmeControl
function (maxIter = 50, msMaxIter = 50, tolerance = 1e-06, niterEM = 25,
msTol = 1e-07, msScale = lmeScale, msVerbose = FALSE, returnObject =
FALSE,
gradHess = TRUE, apVar = TRUE, .relStep = (.Machine$double.eps)^(1/3),
minAbsParApVar = 0.05, nlmStepMax = 100, optimMethod = "BFGS",
natural = TRUE)
I was reading on the R listserve that lmer from the lme4 package may be
preferable to lme (for convergence problems) but lmer seems to need you to
put in starting v...

t.test in a loop
Hi All,
I've been having a little trouble with creating a loop that will run a a
series of t.tests for inspection,
Below is the code i've tried, and some checks i've looked at.
I've used the get(paste()) idea as i was told previously that the use of the
eval should try and be avoided.
I've run a single syntax to check that my systax is correct and works
without any problems
