I tried doing that and this is what I go:
dlg <- aDialog(items=list(
ProtienCode=stringItem("")
),
OK_handler=function(.) { # . is reference to dlg object
values <- .$to_R()
f <- function(ProtienCode)
pdb <- read.pdb(.$get_ProteinCode())
#cat("ProteinCode is",ProtienCode,"\n")
do.call(f, values)
}
)
dlg$make_gui()
with this error message
Error in function (ProtienCode) : could not find function "read.pdb"
Do you know how to get rid of this error?
