Plotting Simple Data in R

Question

I have a comma separated file named foo.csv containing the following data:

scale, serial, spawn, for, worker
5, 0.000178, 0.000288, 0.000292, 0.0003         


        

Answer 1

In your example,

plot(scale, serial) 

won't work because scale and serial are both data frames, e.g.

class(scale)
[1] "data.frame"

You could try the following and use points(), once the plot has been generated, to plot the remaining columns. Note, I used the ylim parameter in plot to accommodate the range in the third column.

data <- read.csv('foo.csv', header=T)
plot(data$scale, data$serial, ylim=c(0,750))
points(data$scale, data$spawn, col='red')
points(data$scale, data$for., col='green')
points(data$scale, data$worker, col='blue')
