error returned when trying to map by county, but not by state

[ghost]

I am getting the following error

choroplethr(df_pop_county, "county", title="2012 Population Estimates") Error in if (nrow(layer_data) == 0) return() : argument is of length zero

If I make a state level request

choroplethr(df_pop_state, "state", title="2012 Population Estimates")

It works as expected.

It appears that df_pop_county is at least initialized

head(df_pop_county) region value 1 1001 54590 2 1003 183226 3 1005 27469 4 1007 22769 5 1009 57466 6 1011 10779

I've reinstalled the choroplethr package, to no avail. I'm using a Mac OSX 10.9.4, R.Version() = $version.string [1] "R version 3.0.3 (2014-03-06)"

Note, I have a county level data set that I've created, and the following call does work as expected: choroplethr(tempDf, lod="county", num_buckets=6, states="WA", warn_na=F)

I have seen that error. I can't remember the exact cause, but I seem to remember that it was an issue with dependencies not matching. Can you type library() for all the packages listed in the dependencies and try again?

library(ggplot2)
library(plyr)
library(Hmisc)
library(grid)
library(acs)
library(stringr)
library(testthat)
library(maps)
library(zipcode)
library(knitr)

Hi,

Thanks for the quick response, I really appreciate it!!

That seemed like a good idea, but it didn’t fix it. I restarted R and did the sequence you provided, but I get the same error. Other functions still work.

Hi Steve,

Please try the following:

1. updating your version of R (the current version is 3.1.1)
2. updating all your packages by typing update.packages()

and trying again.

I am running 3.1.1. I just uninstalled all my packages and reinstalled choroplethr and it worked fine. For reference, here is my script. Also, I am running mac os x 10.9.4 as well:

remove.packages( installed.packages( priority = "NA" )[,1] )
install.packages("choroplethr")
library(choroplethr)
data(choroplethr)
choroplethr(df_pop_county, "county", title="2012 Population Estimates")

Cool!! I was actually running 3.1.1 on my main machine but not on the secondary one. The error was being produced on both. However, the remove.packages and install.packages must have been the key, it's working now.

Thank you very much!!

Great. I'll close the ticket. Thank you for using choroplethr!
