Mapping code not working
Your error references a column that is not mentioned in your sample line of code. . suggesting that something else is going on. The usual advice applies, as the footer always says:

One thing mentioned in the Posting Guide is that you should post in plain text, since HTML format can lead to confusion on our end (what you see is not necessarily what we see).

I have a data frame of data I want to map. I've already created a base map called 'England'. The data frame is as follows: 'data.frame': 2303 obs. of 13 variables: $ Response.ID: int 1 2 3 4 5 6 7 8 9 10 ... $ Year : int 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 ... $ Sex : Factor w/ 2 levels "f","m": 1 2 1 1 1 1 2 2 2 2 ... $ Ethnicity : Factor w/ 6 levels "","Black","East Asian",..: 6 6 6 6 6 6 6 6 6 6 ... $ Age : int 24 22 16 22 49 21 62 36 21 75 ... $ Age.Group : Factor w/ 5 levels "> 80","16-20",..: 3 3 2 3 4 3 5 3 3 5 ... $ Town : Factor w/ 885 levels "Abbey Hey","Aberdare, Conwy",..: 781 259 421 259 229 92 836 276 594 276 ... $ Postcode : Factor w/ 987 levels "AB10","AB16",..: 888 888 886 888 884 685 270 301 78 300 ... $ Region : Factor w/ 11 levels "East Midlands",..: 9 9 9 9 9 9 9 9 9 9 ... $ Latitude : num 50.3 50.3 50.3 50.4 50.5 ... $ Longitude : num -3.66 -3.8 -3.61 -3.65 -3.52 ... $ Bread : Factor w/ 8 levels "Bap","Barm","Batch",..: 7 7 1 7 7 7 7 7 7 6 ... $ Icon : Factor w/ 8 levels "measle_brown",..: 2 2 1 2 2 2 2 2 2 8 ... The following command works on another similar data frame, but not on this one.
England+stat_bin2d(aes(x=Longitude,y=Latitude,color=factor(Bread$Bread),fill=factor(Bread$Bread)),size=.5,bins=200,alpha=.5,data=Bread)
It returns the following error: Error in Bread$Sex : $ operator is invalid for atomic vectors What am I doing wrong here? I'm new to R, so I'm not sure if this is easy or difficult to solve. Thanks in advance! [[alternative HTML version deleted]]
