Dear All,
I would be grateful if you can tell how can I suppress the legend
(automatically created) when I plot a groupedData.
suppose that I have data farme df_0 which contains the following columns:
ID represents the clusters, t represents time of observation, Y: the variable
of interest and X a binary covariate. Then:
df_1 <- groupedData(Y ~ t | ID)
plot(df_1, outer ~X)
This gives me the plot (Y ~ t) for each cluster with a legend containing all
the clusters.
How can I drop the legend?
Thanks you very much,
Bernard,
