Description Usage Arguments Value Author(s) See Also Examples

Split a data frame into a list of blocks (either by rows or by columns)

1	df_to_blocks(DataFrame, blocks, byrow = TRUE)

`DataFrame`	a data frame to split
`blocks`	either a list or a vector indicating the blocks. If `blocks` is a list of vectors, then the length of each vector defines the size of the blocks. If `blocks` is a vector, then each element represents the size of the blocks.
`byrow`	logical. If `TRUE` (the default) the data frame is split by rows, otherwise the data frame is split by columns

A list of data frames

# say you have a data frame

# list defining the blocks
row_blocks = list(1:3, 4:6, 7:9)

# split data into list of blocks (by rows)
df_to_blocks(iris_df, row_blocks)

# split data into list of blocks (by columns)
