[R] Mapping code not working

[Chris Montgomery]

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!
