About stepwise regression problem
First of all, I have GAMs
noxd<-gam(newNOX~pressure+maxtemp+s(avetemp,bs="cr")+s(mintemp,bs="cr")+s(RH,bs="cr")+s(solar,bs="cr")+s(windspeed,bs="cr")+s(transport,bs="cr"),family=gaussian
(link=log),groupD,methods=REML)
Then I type " summary(noxd)". and show
Family: gaussian
Link function: log
Formula:
newNO2 ~ pressure

How to save the output of "split" command as series of .csv files
Hello,
I am looking for a way to quickly split a data frame containing daily
temperature readings into a series of individual data frames, one for each
year, in order to save them as individual .csv files which will be named
according to Year. I would prefer not to use a series of "subset" commands
given that there are a differing number of years for the various location.

Very confused with class
Hi all,
I am very confused with class.
I am looking at some weather data which I want to use as explanatory
variables in an lm. R has treated these variables as factors (i.e. with
different levels), whereas I want them treated as discretely measured
continuous variables. So I need to reassign the class of these
variables, right?
Indeed, doing
class(southwest$pressure)

Question about GAMs
hi! I hope all of you can help me this question
for example GAMs:
ozonea<-gam(newozone~
pressure+maxtemp+s(avetemp,bs="cr")+s(ratio,bs="cr"),family=gaussian
(link=log),groupA,methods=REML)
formula(ozonea)
newozone ~ pressure + maxtemp + s(avetemp, bs = "cr") + s(ratio,bs = "cr")
#formula of gams
coef(ozonea) # extract the coefficient of GAMs

Find values from one dataframe between certain values in another dataframe
Hi all,
I have a 2 files, one with a series of beginning and end times of animal
dives in (lets call it dives). The other file is readings from a time-depth
recorder, there is a datetime reading for every second, a temperature and
light level reading (lets call it tdr).
Now I want to say from the file dives, using the start and end time of the
dives, go to the tdr file and find me the

Data Parameter extract
Hi,
So I have a set of data, hourly temperature, where each temperature is set
up like this:
Time Temp
1.04 8
1.08 10
etc. Where "1" corresponds to a day (say monday is "1", tuesday is "2") and
the decimal value corresponds to an the hour of the day.
I have several thousand of these readings over several months. What I would
like to do is
