R

Sumendar Karupakala has a bunch of errors you might find in R, as well as their explanations and fixes:

#pull out the animals which are dogs
animaldata[animaldata$Animal.Type == “Dog” ] # throuws an error
Error in `[.data.frame`(animaldata, animaldata$Animal.Type == “Dog”): undefined columns selected
Traceback:
1. animaldata[animaldata$Animal.Type == “Dog”]
2. `[.data.frame`(animaldata, animaldata$Animal.Type == “Dog”)
3. stop(“undefined columns selected”)
In [8]:
#fixed error
animaldata[animaldata$Animal.Type == “Dog”, ] # missedout comma with in the bracket

Some of it is basic syntax; others are a bit nastier.
