I am trying to fit a sine function on one year of wind data. I have
two
questions below.
Looking around on the net I managed to get the following:
Sine Equation: y = a + b * sin( c + d*x )
b is the amplitude, c is the phase

Dear R users,
I want to create a proper .Rd file for the show method for an S4 class.
I am encountering problems in the \usage{} line, I guess. An example:
setClass(testClass,
representation(a=character))
setMethod(show, testClass, function(object){
})
The .Rd file:

Hi,
The data set is indeed highly redundant, mostly zeros (which means I
could use sparse matrices, but that's another issue). I have posted an
octave ascii file here:

and a .mat file here:

A few more
for data.frame: for(j in grep('Laser_', names(m)) lines(m[,j])
for matrix: for(j in grep('Laser_', colnames(m)) lines(m[,j])
or
for(j in 2:4) lines(m[,j])
Shorter could be worse if you insert additional columns later.

Dear Sir/Madam:
I am sorry if this is a simple question. I have downloaded the source code for
R but could not find the source file that has the rnorm function definition.
Could you please let me know which file has the function? Also, in general, how
do I find the source file of a given

I've just tentatively put code to fix this in place in R-devel. By
default it is not enabled, because if it goes wrong it could really mess
things up. To enable it, set
options(install.lock=TRUE)
before installing or updating binary packages in Windows. It will slow
down all installs, so
