Hello,
Sorry, there's a close parenthesis too many in the call to boot, the
very last one.
Delete it and it runs with no errors.

Hi Vicci,
It's very clunky, but I think it will do what you want.

Dear all,
if the attachment didn´t arrive, maybe it works now.
I would like to substract the "IN" values (= the air which goes into the
chambers) for "d13C", "ppm_CO2" and "ppm_13CO2"
from the "d13C", "ppm_CO2" and "ppm_13CO2" for every single chamber.

Dear R-experts,
I am trying to get the bootstrapped confidence intervals of Mean squared error
(MSE) for a (G)AM model. I get an error message.

Jeff's advice is sound, but as I have a bit of time on my hand, I'll take a

You hope... but no... not really. You need to enhance your question with a
(minimal) example of the data just after importing into R, and another example
of what you think the result should look like. Also, you should provide your
current best guess at what a calculation would include expressed
Dear all,
I hope this is the right way to ask questions.
I have a problem with R regarding the detection of the measurement of a
specific sample_id (see example file attached). I have to substract the
"IN" values (means the air which goes into the chambers) from the values of
"d13C", "ppm_CO2" and
