A function for checking if an object contains a strategy.
Value
A logical value of TRUE if the 'strat' attribute of 'x' is set,
otherwise FALSE.
Details
Designed to be used by ichimoku functions that are either S3
methods for class 'ichimoku' or after validation that 'x' is an ichimoku
object, hence there is no check on the class of 'x' within this function.
Examples
cloud <- ichimoku(sample_ohlc_data)
strat <- strat(cloud)
# TRUE:
hasStrat(strat)
#> [1] TRUE
# FALSE:
hasStrat(cloud)
#> [1] FALSE
