After making changes to a data frame using gdf, how do I retrieve the dataframe I have created?
Sample code:
require("gWidgets2RGtk2")
## Sample Data frame
x<-data.frame(a=c(1,2,3),b=c(4,5,6))
## Create Widget
w<-gwindow("gdf")
a<-gdf(x,cont=w)
## Makes some changes using widget
svalue(a)
> NULL
Managed to figure out the solution, although it doesn't seem very logical!
a #Doesn't work
# Object of class GDf
a[1:nrow(a),1:ncol(a)] # Works
# a b
# 1 1 4
# 2 2 5
# 3 3 6
# NA NA
str(a[1:nrow(a),1:ncol(a)]) #Shows that this is a data frame
# 'data.frame': 4 obs. of 2 variables:
# $ a: num 1 2 3 NA
# $ b: num 4 5 6 NA
To retrieve the value of the gdf object, you need to do the following (using your example):
a[]
This doesn't seem to be documented in ?gdf, so maybe a bug report is in order.
