Readr loses negative values when reading

[vzemlys]

Compare the following:

library(readr)
library(dplyr)
read_csv("data.csv") %>% filter(Geographies == "Lithuania") %>% .[["Q1 2009"]]
read.csv("data.csv") %>% filter(Geographies == "Lithuania") %>% .[["Q1.2009"]]

The read_csv drops the negative sign.
