exp <- conv_hs(exp): Error in conv_hs(exp) : could not find function "conv_hs"

[LDHHAHA]

I run your code, and there is a error when it comes to: exp <- conv_hs(exp): Error in conv_hs(exp)

Error in conv_hs(exp) : could not find function "conv_hs". I need know which package i require for this function.

Thanks a lot.
