Python in .Rmd files

Load libraries

Just like R, you can use Python in .Rmd files! Here we import our libraries

import pandas as pd

Load data

Let’s use pd.read_csv to load the titanic data and view the top of the data set:

titanic  = pd.read_csv("data/titanic.csv")
titanic.head()

##    pclass  survived  ...   body                        home.dest
## 0       1         1  ...    NaN                     St Louis, MO
## 1       1         1  ...    NaN  Montreal, PQ / Chesterville, ON
## 2       1         0  ...    NaN  Montreal, PQ / Chesterville, ON
## 3       1         0  ...  135.0  Montreal, PQ / Chesterville, ON
## 4       1         0  ...    NaN  Montreal, PQ / Chesterville, ON
## 
## [5 rows x 14 columns]

plot data

Passing the python data frame into ggplot using py$data_frame syntax to make my scatterplot (what can I say, I love ggolot2…).

## Warning: Removed 264 rows containing missing values (geom_point).

ggplot2::ggplot(py$titanic, aes(x = age, y = fare)) +
  geom_point()

And inline python code within markdown text!

Here we find the destination of the first passenger:

first_dest = titanic["home.dest"][0]

The destination of the first passenger is St Louis, MO.
