Plotting multiple lines from a data frame in R

Question

I am building an R function to plot a few lines from a data table, I don\'t understand why this is not working?

data = read.table(path, header=TRUE);
plot(da         


        

Answer 1

Or with base:

data <- data.frame(time = seq(0, 23), noob = rnorm(24), plus = runif(24), extra = rpois(24, lambda = 1))
plot(extra ~ time, 
  data = data, 
  type = "l", 
  ylim = c(min(data[ ,-1]), max(data[ ,-1])),
  ylab = "value")
lines(data$time, data$plus, col = "steelblue")
lines(data$time, data$noob, col = "pink")
