How to do a trig regression
...nt.
y, x are input vectors.
The equation I put into R: lm(y ~ sin(2*pi*x/360)^2)
This equation is missing the c and I dont get the right answer.
Also, I dont know how to plot the lm over the x values instead of the
indices.
Any help is sincerely appreciated.
Thank you all very much.

R not recognized in command line
...bin\i386
but only if I run the batch file...its not natively recognized (if I were to
type 'R' at the prompt in DOS, its not recognized)
I would appreciate any help in this matter.
Or should I do something else so that I can try rpy2?
Python version 2.6.6
R 2.12.1
rpy2 2.0.8

Help with time in R
Hi,
I have a problem with the time formatting in R. I have entered time in the format "MM:SS.xyz" and R has automatically classified this as a factor, but I need it numerically. However when I use as.numeric() it gives me totally different numbers. Is there any way I can tell R to read thes input as a number?
Thank you very much

Time Variable and Historical Interest Rates
...d that there was a way to read data
from a website into R if you know the url. Would this help in getting the
interest rates of other countries? (I believe the function is aptly named
"url"). Could someone provide an example, please?
All help is very much appreciated.
Sincerely,
Aaditya Nanduri

Where to find the p-value of a correlation test
Hey everyone,
I hope this finds you in good cheer.
I just have a quick question: What is the function that outputs the p-value
for correlation?
cor(x,y) only provides the R value. I would like the p-value associated
with it.
Thank you all for your help!

How to optimize or build a better random forest?
Hello Everyone!
It's been a while since I last posted a question! Hope everyone has been
doing well!
~~~ CONTEXT ~~~
I have recently entered a beginner-level competition on kaggle. The
goal of the competition is to build a model that predicts who did/did not
survive on the Titanic.
I decided to use random forests as I have been wanting to learn the
algorithm and the competition
