[R-sig-eco] Problem with function iucn_summary() of taxize package, returning error in strsplit()

[Eduard Szöcs]

Hai Augusto,

thanks for reporting this bug!

I just pushed a fixed version, where NA is returned when the IUCN-API 
does not return anything.
You can install the newest version from github via:

install.packages("devtools")
require(devtools)
install_github("taxize_",  "ropensci")
require(taxize)


Happy holidays,

Eduard
