is not the case.
Could someone gimme some light?

Detect file change
Hello everyone!
How can I detect if a folder have changed (sync logic) than run a script
if it's true?
I found this script over the net, but I think it's such complicated for
that simple thing...

ENC: Using lm() combined with sapply
...regressions changing the dependent variables for the same period. I believe your solution might be similar to that one, just making the window dynamic instead. I used a lapply to store regressions and sapplys to extract stats from the lm()s. Please check the attachment and hope it?s useful.

Writing Text into Plots

Hello,
I have a simple question on the text() method in plots, e.g.:
text(3,4,adj=1,cex=1.0, expression(alpha == beta))
I know there exists a lot more like frac(), etc which could be used for
expression. But a help(frac) doesn't return any results - where do I
have to look for a documentation of possible text commands?

Linear regression - several response variables vs few ind variables
Hi all,
I need to run several simple linear regressions at once, using the
following data. Response variables: Bird species (sp 1, sp2, sp3...spn).
Independent variable: Natprop - proportion of natural area. covarate:
Effort = hours). One single linear regression would be: lmSp1 <- lm(sp1~
natprop + effort). However, I need to run this linear regression for all
bird species that I have

I'd like to print out an histogram of some experimental data and add a
smooth curve of a normal distribution with an ideally generated
population having the same mean and standard deviation like the
experimental data.
The experimental data is set as vector x and its name is set to

Linear multivariate regression with Robust error
Dear all,
i am doing linear regression with robust error to know the effect of
a (x) variable on (y)other if i execute the command i found positive
