R plots: customize point attributes

I can easily specify the data point shape (pch) by adding a column to my data. I am trying to understand why this does not also work for outline color (col) or fill (bg). Note that the shapes do have attributes col and bg. Below is a subset of my data and the code, which works for pch, but not for col or bg. Thanks!

X   Y   Shape   Line    Fill
104 87.238  22  "blue"  "pink"
693 255.985 21  "gold"  "gold"
15  33.069  24  "red"   "white"
414 289.072 24  "red"   grey
plot(data[,1:2],log="xy",pch=data[,3],col=data[,4],bg=data[,5])

You need

plot(data[,1:2],log="xy",pch=data[,3],
    col=as.character(data[,4]),bg=as.character(data[,5]))

Line and Fill were being treated as factors and therefore integers, not the strings that you intended.
