[R-sig-Geo] Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection

[Anisha Kaul]

Greetings,

R version 2.15.1
RgoogleMaps version 1.2.0
openSUSE 11.3, 64 bit


The source code file 'mow.R' now contains:
_______________________________________
library(RgoogleMaps);
png(filename="RgoogleMaps-package_%03d_med.png", width=480, height=480);

MyMap <- GetMap(markers='&40.702147,-74.015794,blues%7C40.711614,-74.012318,greeng%7C40.718217,-73.998284,redc',
destfile="MyTile1.png");
_______________________________________



This results in the following new error:
_______________________________________
> source('mow.R')
[1] "Note that when center and zoom are not specified, no meta
information on the map tile can be stored. This basically means that R
cannot compute proper coordinates. You can still download the map tile
and view it in R but overlays are not possible. Do you want to proceed
? (y/n)"

I have to say that I don't know what does this function do:
`png(filename="RgoogleMaps-package_%03d_med.png", width=480,
height=480);`
I tried this example from here:
http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=RgoogleMaps:RgoogleMaps-package

If there is some other information that you want me to include, please
let me know.
What's the way to correct this error?
