Barplots无法正确绘制R中的频率

Question

Struggling to plot a barplot where the height of each bar is related to the value in a column (in this case, freq). Table name is Tag_Count_2

Tag.1  freq
Hello  3
My     4
Name   10

I tried:

Counts<-table(Tag_Count_2$freq)
barplot(Counts)

But it plots the # of times values under Tag.1 share the same freq. I also tried:

barplot(Tag_Count_2, height=freq)

But it said freq wasn't found.

Answer 1

Are you looking for

barplot(Tag_Count_2$freq)

You don't need the table command in this case as you already have the frequency .
