如何在R Studio中将两个数据集合并为一个并用两个数据集绘制一个图形

Question

Currently I have combined the Apple stock market and the Samsung stock market from 2014- 2018. I have combined the Date,Open,High, low and Close using cbind and changed the names so it says Apple/ Samsung.

My problem is with the graph, Now my dataset is combined in columns so I feel like this might be part of the problem, but none the less I would prefer to keep it like that. I would love a graph that would have both of the open figures on it over the years.

If I just use plot(Total$OpenApple, Total$OpenSam) the plot is a huge block compared to the line graph I would like.

Thanks.

Without any example data its difficult to understand your problem fully. However, I would try using the ggplot2 package and dplyr package. Then you can change your data so that OpenApple and OpenSam are both part of the same column, and then use a function from ggplot2 to change the colors of your lines based on what group they are a part of.
