​This warning is benign -- it's a long-stanging buglet in signal package (which I thought

was fixed some time ago, but apparently reappears again):

the spectral power ​must be positive, but due to finite numerical precision one could get

it negative.

​I can reproduce ​

error: set: "cameratarget" must be finite

​(which is serious)

but I have not figure out where it is coming from. ​

​Perhaps you should file a bug report.​
