[R-sig-Geo] plotGoogleMaps - Represent Text on map

[Abhishek Kapoor]

Hi Sir,

is it possible to plot map using factor variable?

I am trying to plot ATMs, Hospital, and restaurant location (Lat/Long) and
with address but i m not getting desired result.

Below is the code

 
eq <- read.csv ('C:/Users/abc/Desktop/2013_08_01_NCR_Master.csv')
str (eq)

'data.frame':   13430 obs. of  6 variables:
 $ Type       : Factor w/ 3 levels "ATM","Hospital",..: 2 2 2 2 2 2 2 2 2 2
...
 $ Lat        : num  28.5 28.5 28.4 28.6 28.7 ...
 $ Lng        : num  77 77 77 77 77 ...
 $ PhoneNumber: Factor w/ 5562 levels "","0","011 2004 4406",..: 4922 1 2610
1 1 2669 1 2652 1 4075 ...
 $ Address    : Factor w/ 13394 levels "???, IGI Airport T3 Road, IGI
Airport, New Delhi, DL",..: 11064 11071 13208 9306 12497 2644 10809 9722
6499 12089 ...
 $ Type1      : int  2 2 2 2 2 2 2 2 2 2 ...

coordinates(eq) = ~Lng + Lat
proj4string(eq) = CRS("+proj=longlat +datum=WGS84")
eq <- SpatialPointsDataFrame( eq , data = data.frame( id = row.names( eq ) )
)

ma<-plotGoogleMaps(eq,zcol="Type", colPalette=c("#FFF7BC",
"#FEC44F","#D95F0E"),filename='myMap82.html',mapTypeId= 'TERRAIN',
fitBounds=T)

but it is not producing desired results
I want only 3 color bubbles by "Type" - ATM, Hospital & Restaurants 

I hope you can help me, this is my first time in R. 

I am using Windows and R is 3.0.2
Thanks in advance

Regards
Abhishek
