This can be readily used, i.e. for plotting

library(ggplot2)
ggplot(df) +
  geom_line(aes(x = date, y = indpro))

Vintage data

When using get_alfred_series for downloading real-time data sets, there will be an additional column for the respective vintage dates.

df_vintages <-
  get_alfred_series("GDPC1", "rgdp",
                    observation_start = "2007-05-31",
                    realtime_start = "2008-05-31", realtime_end = "2009-03-30")
df_vintages

Because of its output being a tidy data frame, it is easy to visualise revisions by

library(ggplot2)

ggplot(df_vintages) +
  geom_line(aes(x = date, y = rgdp, colour = as.factor(realtime_period))) +
  theme_bw() +
  theme(
    legend.title = element_blank(),
    legend.position = "bottom"
  )
