Error when calculating heatwave indices

[oliverangelil]

I'm trying to calculate heatwave frequency from a netcdf file with daily tasmax values.

Firstly, calculating txx works, with this line (so seems I'm having no package problems):
indices=c("txx")

But when using this: indices=c("hw")

The following error pops up:
Error in if (cdx.meta$var.name[i] == "rxdday") { :
missing value where TRUE/FALSE needed
Calls: create.indices.from.files

Do these heatwave metrics require reading in an additional "threshold" file or should one just be able to change the "txx" to "hwf"?

[oliverangelil]

To calculate the "hw" indice, the target netcdf file needs to have both tasmin and tasmax in the file:
vars=c(tmax="tasmax", tmin="tasmin")
If only heatwave metrics based on tasmax are of interest, you can just use dummy data to fill up tasmin.
