Reading CSV file into Julia

As for someone experienced in R I naturally look for data.frame-like structure in Julia to load csv file into it. And luckily it is present and seems to work pretty well. You need to install package called “DataFrames” to operate on R-like dataframes:

Pkg.add("DataFrames")

and load it after installation:

using DataFrames;

The whole documentation is available here. For now we will try to load simple CSV file and play with it. You can use iris dataset. It is a toy dataset meant for various machine learning tasks. Lets download it and read into a variable called iris

iris = readtable("iris.csv")

Warming up

Here it goes. This is my first blog entry with the great purpose to learn Julia language from scratch. The motivation for such is knowledge, of course, but some sort of convenience as well. From what I read already I conclude Julia is promising tool for scientific computing being described as fast and elegant and my goal here is to find out how it’s gonna suit me. Throughout the blog entries you read I will try to solve many small problems you may encounter yourself, so I really hope someone will find whole thing useful.
