Hello everyone,

It's been some time since I've had to use R for school work, and I've barely (almost never) used it since the last course I took that required it. This class's final assignment requires brief use of R, and I've hit a sticking point.

The assignment requires us reading two files (call them df1 and df2 for the sake of this post) to plot on an x-axis, then counting the number of occurrences on each date within the data series. The layout of each data series follows this format:

df layout

The homework calls for us to plot df1 in black and df2 in red, both in the same graph on the x-axis, with the number of occurrences on a particular date on the y-axis.

From what I understand/remember, I'm trying to use something similar to:
plot(df1, type='o', col='black', xlab='Date', ylab='Loss', main='# of Occurrences')
lines(df2,col='black')

But I'm getting this crazy result:

Can someone help me out and give me a nudge in the right direction?

Thanks in advance!
