In the qmodel when specifying +year, is the resultant trend actually linear? #75

The example appears as Figure 33 in the a4a technical document. The associated qmodel is: qmod <- list(~s(age,k=4) + year) In Figure 33, the trend across time for the youngest age appears to be non-linear (the line curves). Is this a plotting issue, are an issue with the calculation?

Nope, should be linear in the log scale ... need to fix the documentation.
