Renaming period in plance / overwrite create Error: Invalid period name: Jan

[paulrougieux]

I am trying to use gg_subseries on a tsibble. I noticed what appears to be a bug due to renaming in place. Here is a reproducible example.

# Create monthly data from the 
library(feasts)
# Create dates
period <- seq(as.Date("2000-01-01"), as.Date("2016-12-31"), by = "1 month")
# Create some random walk values
set.seed(4)
y <- cumsum(rnorm(length(period)))
df <- data_frame(period = period, 
                 y = y, 
                 country = "ZZ") %>% 
    # Convert period to a yearmonth object
    mutate(period = tsibble::yearmonth(period)) %>% 
    as_tsibble(key = country, index = period) 

df %>%
    gg_subseries(y)
# Error: Invalid period name: Jan

When I mutate the period variable to a new name, the error doesn't appear

df2 <- data_frame(period2 = period, 
                  y = y, 
                  country = "ZZ") %>%
    # Convert period to a yearmonth object
    mutate(period2 = tsibble::yearmonth(period2)) %>% 
    as_tsibble(key = country, index = period2) 

df2 %>%
    gg_subseries(y)

Thanks, should be fixed now.

Thank you,

Issue fixed in the reproducible example above after doing remotes::install_github("tidyverts/feasts").
