how to get geocode in R?

i have tried 2 approaches to get the long lat of location.

install.packages("maptools")
library(maptools)
A1 <- data.frame(A1= c("Dordrecht", "Berlin", "New York", 
                                    "Batu Pahat", "Edinburgh"), 
                                    stringsAsFactors = FALSE)

result <- lapply(A1[, 1], geocode_OSM)

or


A2_df <- mutate_geocode(A1, loc)

but both do not work

        loc
  1    Dordrecht
  2    Berlin
  3    New York
  4    Batu Pahat 
  5    Edinburgh

any ideas to get the respectively code without API key?

    library(tmaptools)

geocode_OSM(A1$A1)
