for loop to create line plots for individual columns in r

Question

I'm brand new to r and can't seem to figure this out. I have a csv and need to plot each column as a its own unique line plot, and then output those plots to a csv. Here's what I have for the plotting, however when I simply run the code to create the plots nothing is outputted in r-studio .

for(i in 3:50){
  x <- data[,i]
  y <- data[,2]
  plot(x,type="l", main=names(data[i]), ylab="cases", xlab="month")
}

Does anyone have any suggestions on how to make this work? I just need to create individual plots for each column (each column corresponds to an individual country), and then output all of those plots onto one single pdf .

Answer 1

Something like this should work (but you did not provide a sample of the data to test it):

pdf("myplots.pdf")
for(i in 3:50){
  x <- data[,i]
  y <- data[,2]
  plot(x, y, type="l", main=names(data)[i], ylab="cases", xlab="month")
}
dev.off()

The file will be in your current working directory ( getwd() ). Each page will be a separate plot.
