Dear Remko,

# Code for you question

df <- read.table(text="
                       lat long
                 -33.611137 150.74058
                 -33.611255 150.740684
                 -33.61135 150.740789
                 -33.611089 150.740648
                 -33.611201 150.740757
                 -33.61131 150.740863", header=TRUE)
coordinates(df) <- c("long","lat")
proj4string(df) <- CRS("+proj=longlat +datum=WGS84")


ic=iconlabels(attribute=rep("",6),  # icon label
           colPalette=NULL,  # color
           at=NULL,
           height=10,  # icon height in pixel
           icon=TRUE,  # set icon
           scale=0.4 )  #set icon scale

m=plotGoogleMaps(df, filename="tmp.htm",
                 iconMarker=ic )

# Or you can use your icon

m=plotGoogleMaps(df, filename="tmp2.htm",
                 iconMarker=rep('
http://maps.google.com/mapfiles/kml/paddle/pink-blank.png',6) )

Best,
