Hi: I have one million names of city and their population and want to make a hash so that by giving key = city, the hash function will return its population.
I use the hash package in R as follows: h <- hash(c(as.vector(df$city)), c(as.vector(df$population))) But getting the following error: Error in assign(keys[[i]], values[[i]], envir = hash@.Data) : variable names are limited to 10000 bytes How can it be solved? Thanks: John ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
