Converts the bit representation of an integer into a vector of integers
Usage
int_to_intMask(i, length)
Value
A vector of integer containing 1 or 0
Arguments
i
A 32 bit integer
length
Integer length of the bitmask to produce, must be <= 32
Details
Converts an integer to a vector of ones and zeroes. Used as a helper
function for full_embedding_search, it allows more compact storage of bit masks.
The result reads left to right, so the one bit will have index of one in the
vector corresponding to lag 1 in an embedding. Works for masks up
to 32 bits
he <- embed(henon_x, 17)
t <- he[ , 1]
p <- he[ ,2:17]
mask <- int_to_intMask(7, 16) # pick out the first three columnspn <- select_by_mask(p, mask)
gamma_test(predictors = pn, target = t)
