When I subtract two dates in R, I get the result seen below.
How would you extract only the number from this result without getting all the associative text? Is there a way to do it without having to write a parsing function?

We can convert to numeric wiwth as.numeric/as.double
as.numeric(diffObj)
based on the
methods(class = 'difftime')
According to ?difftime
The as.double method returns the numeric value expressed in the specified units. The units of a "difftime" object can be extracted by the units function, which also has a replacement form
A reproducible example would be
out <- Sys.Date() - (Sys.Date() - 2)
out
#Time difference of 2 days
as.numeric(out)
#[1] 2
units(out)
#[1] "days"
