you can try SpatialPointsDataFrame() in sp package.
for example:

library(sp)
loc <- data.frame(x=c(23.1,19.0),y=c(43.2,45.5),value=c(200,100))
spdf <- SpatialPointsDataFrame(loc[,1:2], loc)

Subject: [R-sig-Geo] Latitude Longitude to SPDF
Hi Team,

Need your guidance in building SPDF objects from Latitude, Longitude
Information available.
I am using package "plotGoogleMaps" which is really awesome but it requires
SPDF objects to build the maps.I have a data frame which have Latitude and
Longitude information and wanted to convert it in SPDF for making maps.

Please help me to find suitable package or function to convert it. Or if I
am missing something. I am really sorry but have very less experience when
dealing with Spatial Data.

Best Regards,


Bhupendrasinh Thakre
