df <- data.frame(
  stringsAsFactors = FALSE,
  date = as.Date(c("2019-01-01", "2019-02-01")),
  value = c(1, 2)
)
with_locale(new = c("LC_TIME" = "es_ES"), code = plot(df$date, df$value))
## Compare with:
#  plot(df$date, df$value)

## Month names:
with_locale(new = c("LC_TIME" = "en_GB"), format(ISOdate(2000, 1:12, 1), "%B"))
with_locale(new = c("LC_TIME" = "es_ES"), format(ISOdate(2000, 1:12, 1), "%B"))

with_locale(new = c("LC_MONETARY" = "it_IT"), Sys.localeconv())
with_locale(new = c("LC_MONETARY" = "en_US"), Sys.localeconv())
