Could not find function "cbind.na"

Question

I am using R:

library(qpcR)
final<-cbind.na(datum_seq, amb.temp)
Error: could not find function "cbind.na"

I looked on the Internet, and this suggests that I need to have an updated version of R and qpcr package.

Confirmed at sessionInfo(), I have the latest version. Could there be another reason why he cannot find the function?

Answer 1

cbind.nais an internal variable in the package qpcR. If you must call this function directly, you can do this using qpcR:::cbind.na.

For more information on internal and external variables, see help(':::').

Before using this, pay attention to the following (from the help page):
