**Revolutions**, and kindly contributed to R-bloggers)If you haven't sent your loved one a Valentine's Day greeting yet, it's not too late! Thanks to Guillermo Santos who pointed out an R script from Berkeley's Concepts in Computing with Data course, I created the following Valentine's Day card for my husband:

If you want to make one for your loved one, you can use the R code below (which I modified slightly from the original):

# Source: http://statistics.berkeley.edu/classes/s133/heart.r heart1 = function(name){ t = seq(0,60,len=100) plot(c(-8,8),c(0,20),type='n',axes=FALSE,xlab='',ylab='') x = -.01*(-t^2+40*t+1200)*sin(pi*t/180) y = .01*(-t^2+40*t+1200)*cos(pi*t/180) lines(x,y, lwd=4) lines(-x,y, lwd=4) text(0,7,"Happy Valentine's Day",col='red',cex=2.5) text(0,5.5,name,col='red',cex=2.5) }

I also sent one of these cute science-themed Valentines cards that I bought on Etsy (guess which one).
