Coming from Python, moving to R:

• Python starts at 0, R at 1.
• Docstrings are not a standard thing in R.

Syntax differences

Python	R
index	rownames
nunique()	n_distinct()
min(), max()	range()
len()	length()
Path('/dir/')	file.something('dir/')
range(10)	c(0:9)
type()	class() or typeof()
df.shape	dim(df)

IMPORTANT NOTES:

• In c(1:10) R starts at 1 incl. 10, while Pythons range(10) starts counting from 0 till 10 (generating 10 integers).
• group_by() incl. a group member NA if it is in grouping column. (This is excl. in Python)
• distinct() in R will include NA, use arg. na.rm = TRUE to exclude it. (This is excl. in Python unique.)
• To give a column to a function, use {{column}} in de function to actually call it.
