[R] Plotting two time series in one graph

[Rui Barradas]

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
