Convert matrix to data.frame

An optimised 'matrix' to 'data.frame' constructor.

matrix_df(x, keep.attrs = FALSE)

Arguments

x

a matrix.

keep.attrs

[default FALSE] if set to TRUE, will preserve any custom attributes set on the original object.

Value

A 'data.frame' object. If the matrix has row names, these are retained by the dataframe.

Details

The optimised data.frame constructors are used internally within the package and made available as utilities. Please note that no data validation or checking is performed.

Examples

cloud <- ichimoku(sample_ohlc_data)
mcloud <- as.matrix(cloud)
df <- matrix_df(mcloud)
str(df)
