Dear List,

I run the code below on my Mac and works fine. On Win 7 64-bit, I’m getting
the error message at the bottom.In both cases, I’m using R 2.15.2.

Any clue?

v1 = c(43.6, 43.8, 44.2);       # Latitude for added points

v2 = c(-80, -79.5, -79.0);              # Longitude for added points

v3 = c(20,30,40);               # Size for added points

v4 = c(1, 0.5, 0.2);            # Transparency for added points

v5 = c(551, 426, 500);          # Colors for added points

testData <- data.frame(lat = v1,lon = v2, big=v3, op=v4, col=v5)        #
Group variables together

mapImageData4 <- get_googlemap(c(lon=-79.1, lat=
43.88),zoom=8,maptype="terrain");      # Get map image data

pic4 <- ggmap(mapImageData4) + geom_point(aes(x=lon,y=lat), data=testData,
colour = v5, size=v3, alpha = v4)


The following `from` values were not present in `x`: col, color, pch, cex,
lty, lwd, srt, adj, bg, fg, min, max

Thanks,

Axel.
