Plotting two time series in one graph

R help mailing list-2
Hi

I'm trying to plot two time series in one graph. I tried the following code:


p = ggplot() + 
  geom_line(data = dovrez, aes(x = Date, y = Res), color = "blue") +
  geom_line(data = rqa_df_USD, aes(x = DATE, y = LAM), color = "red") +
  xlab('Dates') +
  ylab('Values')
print(p)

But I got the following error:

Hata: `mapped_discrete` objects can only be created from numeric vectors
Run `rlang::last_error()` to see where the error occurred.

Time indexes of my dataframes (dovrez, rqa_df_USD) are not same. First dataframe (dovrez) has 820 date points. Second dataframe (rqa_df_USD) has 75 date points.

How can I plot these two data in one graph?

Best Regards
Baki Ünal

Hello,

Can you post sample data? For instance, the output of

dput(head(dovrez, 20))
dput(head(rqa_df_USD, 20))


Or maybe you could rbind the data.frames with one column telling which
of Res or LAM the values come from.


Hope this helps,

Rui Barradas
