And note how Michael has changed your code so that your data object
is now named "Final" instead of "Final.csv".

That should work: you are using it before the call to gam?
Try this (verbatim)
library(mgcv)
Final <- read.csv("Final.csv")
ls.str()
search()
sessionInfo()
gam(Atlantic ~ s(depth, bs="sos", k=4) + s(distance, bs="sos",
k=4), data = Final)
and give the output.

I used:

Hi Dontrece,
It looks like you do not have an object "Final" in your active
session.
Could you please show us how you read your data, e.g., what
commands you
used and what's the result of ls()?
As Sarah Goslee mentioned in an earlier post, you probably used
read.table() or read.csv() but you haven't told us (yet).
Regards,
Jorge.-

Now, it read this:
library(mgcv)
This is mgcv 1.7-6. For overview type 'help("mgcv-package")'.
gam(Atlantic ~ s(depth, bs="sos", k=4) + s(distance, bs="sos",
k=4),
data = Final)
Error in inherits(x, "data.frame") : object 'Final' not found

Hi,
If "x" is your data, then
gam(Atlantic ~ s(depth, bs="sos", k=4) + s(distance, bs="sos",
k=4),
data =
x)
will do. See examples in ?gam.
BTW, how did you read your data in R? What's the output of ls()?
HTH,
Jorge

This is my first time running GAMs in R.
My csv file has these column headings:
"X" "Y" "Sound" "Atlantic" "Blacktip"
"Bonnet"
"Bull" "Finetooth" "Lemon" "Scalloped" "Sandbar"
"Spinner"
"Abundance" "Diversity" "Depth" "Distance" "Width"
"System"
"Channel" "Profile" "Bathy" "Slope" "Salinity"
X is longitude and Y is Latitude.
I typed in the code below and received the reply "Error in eval
(expr,
envir,
enclos) : object 'Atlantic' not found".
library(mgcv)
This is mgcv 1.7-6. For overview type 'help("mgcv-package")'.
help("mgcv-package")
starting httpd help server ... done
gam(Atlantic ~ s(depth, bs="sos", k=4) + s(distance,
bs="sos", k=4))
Error in eval(expr, envir, enclos) : object 'Atlantic' not found
I do not have a clue how to fix this problem. Do I have too many
variables
or do I need to remove my x and y from the file? This data is
being
used
to
assess the spatial distribution of shark abundance in relation to
environmental variables. I really cannot remove the x and y
anyway.
Help
would be greatly appreciated.
