Usage

mv(row = 0L, col = 0L)

`col`	number of columns in which to move the cursor. Positive values move the cursor forward; negative values move the cursor backwards.

Details

The user must be in a terminal to use the functionality; it will not work in RStudio or the R GUI.

# move the cursor down one and forward two
mv(1, 2)

# Alternatively, you can specify the coordinates as a single vector.
loc <- c(1, 2)
mv(loc)

# to move to the left one unit (only works if the current column is > 1)
