RGooglemaps Random Geocode Error (reproducible code)

I get a random number of errors that come back as NA when I try to geocode a lot of places using rgooglemaps getGeoCode function. Can anyone tell me why? (Reproducible code below)

library(RgoogleMaps)
library(foreach)
###Replicating a large search data###
PlaceVector <- c(rep("Anchorage,Alaska", 20), rep("Baltimore,Maryland", 20), 
rep("Birmingham,Alabama", 20))
iters <- length(PlaceVector)
###Looping to get each geocode###
geoadd <- foreach(a=1:iters, .combine=rbind) %do% {
  getGeoCode(paste(PlaceVector[a]))
}
geoadd <- as.data.frame(geoadd)
geoadd$Place <- PlaceVector

I get a random number of errors, usually around 15 where the latitude and longitudes in data frame geoadd come back as NA. I could loop it back on the NA's but that seems utterly inefficient. Do others have the same problem with the sample code provided?

I get NA's in the example as well. I once had a problem with looping and geocoding. The problem was that I was hitting googleMaps to fast or with to many request within a minimum time frame. I built in a waiting period with Sys.sleep to solve the issue. The problem is finding the correct amount of microseconds to wait. This depends on your connection and response times of google.
