Dear list,
I'm running an R script which first line is:
#!/usr/bin/Rscript
While running that script from the system console (in Red Hat
Enterprise Linux 6) I got the following error:
Error in plot2(x = sim, y = obs, plot.type = "single", main =
paste("Daily", :
could not find function "hasArg"
Calls: plot_results -> plot_out -> ggof -> plot2
However, if I call EXACTLY the same script from the R console, by using
> source("myRscript.R")
I do not get any error.
As you can see in the error message, the function 'plot_results' calls
'plot_out' (both in the hydroPSO package). Then 'plot_out' calls the
function 'ggof', which in turn calls 'plot2' (the latter 2 in the
hydroGOF package), and 'plot2' has a call to 'hasArg'.
The package 'hydroGOF' exports all its functions by using:
exportPattern("^[^\\.]")
At the other hand, the package 'hydroPSO' does not import any function
of the 'hydroGOF' package, because the call to 'ggof' only occurs within
the 'plot_out' function if the hydroGOF package is detected on the user
machine:
if (!require(hydroGOF)) {
stop("Invalid argument: You don't have the 'hydroGOF' package !!")
} else {
library(hydroGOF)
ggof()
}
Do I have to explicitly import 'ggof' and 'plot2' on the 'hydroPSO'
package in order to avoid this error or is there any better solution ?
