Hi Greg,
Recent mgcv versions use extended quasi-likelihood in place of the
likelihood for (Laplace approx) REML with quasi families (e.g. McCullagh

trying to use the quasi-likelihood directly with REML.

Note that, given C, A and B can be obtained by simple linear regression of y on
sin(Cx). Hence you could avoid nls altogether by a simple search of the minimal
ls solution(possibly robust) over a grid of C values. Or do this to find good
starting values for nls.

That won't work because R has special rules for evaluating things in the
function position. Examples:
*OK*
min(1:2)
min(1:2)
f-min; f(1:2)
do.call(min,list(1:2))
do.call(min,list(1:2)) # do.call converts string-function
*Not OK*
(min)(1:2) # string in function position is

Hi all,
Hello R-List,
I have a question about recoding from a date time object. I have tried using
as.POSIXct objects and Chron Objects, but I can get the what I want.
I need to create a new variable from a date-time object, adding Office Time
for those events that happens between 08:00:00 to

Not sure the replies you received make it clear, but the key point is
that functions are first class objects in R like any other objects
(vectors, lists, data frames) and can be assigned, collected into
structures, indexed, etc. in the usual way. Further, if the value of
any R expression is a
Hi there,
I am trying to compute the autocorrelation in a dataset using R's acf
function. ACF automatically plots the results. This works well except in
some cases xlim doesnt work
data - rnorm(2000,0,1)
acf(data,xlim=c(1,10)) # works - the plot starts at 1
acf(data,lag=100,xlim=c(1,100)) #
I don't know of any package that will do it (or if violating the
marginality principle by having non-nested models even makes sense)
but you could always build your own search through all possible
models. Problem is for a large number of fixed effects this can take a
good bit of time...

Hello all:
I'm trying to use the following code to get commands, comments and results to a

Assuming this is the hexplom function from the hexbin package (it is
best to be specific in case there are multiple versions of the
function you ask about), you can specify lower.panel=function(...){}
for a, and as.matrix=TRUE for c, for b I am not sure what exactly
you want to do, but look at the

Dan,
Thank you very much. That is exactly what I need. What a clever solution.
David, thanks for trying.
Thank you all. I would never be able to figure it out on my own.

All,
I frequently make spreadsheets in Excel in which I rank values in columns
by stop-light colors (red is bad, yellow is OK, green is good).
Image and heatmap expect a matrix in which all the data are in the same
scale, but I frequently have different scales in different columns. ie.

If you must repeatedly append rows to a data.frame,
try making the dataset you are filling in a bunch
of independent vectors, perhaps in a new environment
to keep things organized, and expand each at the same time.
At the very end make a data.frame out of those vectors.
E.g., change the likes of
Hi, John-
Would it be possible to scale the values in each column to fall between 0 and 1
(or standardize them) and use a single color ramp?
