I don't know the specifics of this package, but generally the C code

Hi all,
I'd like to plot the Real and Imaginary parts of some f(z) as two
different surfaces in wireframe (the row/column axes are the real and

There are lots of options since you did not tell us what you want on the

For example if you want more than 6 tick marks/labels, replace xlim=c(0,
3000) with xaxp=c(0, 3000, 12) to get labels every 250 meters instead of
500. Depending on the size of the graph window y

Why would you end up with d1 in your output if you don't have a d1 in your

by making one long column response of R1 on top of R2 on top of R3. Then you
need to make a diagonal X matrix with X1, X2 and X3 bein

Hello everyone,
I'd like to search for certain "expressions" (characters) in my data.frame
and delete the containing columns.
So, for example in the below table, I'd like to delete all columns which
contain the expression "Error". That is, R should delete column C and E from
my data. Any id
I'd be inclined to use predict(ozonea,type="terms") to extract the
estimates of s(ratio,bs = "cr")
that you need. But do you really want newozone - s(ratio,bs="cr") when
you've used a log link?
best,
Simon

I believe the lag() function can be used to rig this up.
Something like sma.365 <- SMA(lag(data, 12), n=120) # Untested, but seems right

I am not an expert on this, but there is a way to check this. You can predict
from a gam using predict(ozonea, newdata=...). In the "newdata" argument you
can specify the X-values of interest to you. Thus, you can compare if your
predictions are the same when predicted directly from the gam or when
Slight addendum, tabulate() ignores zeros so you'll need to do tabulate(y+1).
Table will handle zeros but won't look for values that never appear
(in your example 2 & 4).
