R-将多列绘制为x轴上的年，将行绘制为不同的线

Question

Here's my data frame:

            2010    2011   2012   2013   2014   2015
 A             0     100    164     75    154    110
 B            71      77    136     58    138    136
 C             0       0    132     53     83      0

I'd like to make a line graph in which the years are plotted along the x-axis and and counts are plotted along the y-axis, with rows A, B, and C each having their own line. Is it possible to do this without melting the years into a single variable?

Answer 1

There is a function for this, matplot . Try

matplot(yourData, type="l")
