在R中绘制数据框

Question

I want to plot some data in R. However, when I try to plot my dataframe "bef_ads", a large number of plots are shown together. I just want to get the list inside the data frame and make a normal plot.

Thanks!

dput(bef_ads)
structure(list(V1 = 56660L, V2 = 60616L, V3 = 85913L, V4 = 70709L), 
 .Names = c("V1","V2", "V3", "V4"), row.names = c(NA, -1L), class = "data.frame")

Answer 1

The problem is that your data is in different columns of a data frame with 1 row. When you use plot(...) on this, it treats each column as a different dataset (with just one point, in your case). This is why you are getting all those plots.

So you could transpose the dataframe (to one with one column and 4 rows), and plot that:

plot(t(bef_ads),type="b")

Or you could "unlist" the data frame as suggested in a comment. This basically converts the data frame to a vector and plots that.

plot(unlist(bef_ads),type="b")

Answer 2

For a barplot:

barplot(unlist(bef_ads))
