Applies conditional statements to numeric vectors in H2O parsed data objects when the data are numeric.
h2o.ifelse(test, yes, no) ifelse(test, yes, no)
test | A logical description of the condition to be met (>, <, =, etc...) |
---|---|
yes | The value to return if the condition is TRUE. |
no | The value to return if the condition is FALSE. |
Returns a vector of new values matching the conditions stated in the ifelse call.
Both numeric and categorical values can be tested. However when returning a yes and no condition both conditions must be either both categorical or numeric.
