Variance of a column or covariance of columns.
Compute the variance or covariance matrix of one or two H2OFrames.
h2o.var(x, y = NULL, na.rm = FALSE, use) var(x, y = NULL, na.rm = FALSE, use)
x |
An H2OFrame object. |
y |
|
na.rm |
|
use |
An optional character string indicating how to handle missing values. This must be one of the following: "everything" - outputs NaNs whenever one of its contributing observations is missing "all.obs" - presence of missing observations will throw an error "complete.obs" - discards missing values along with all observations in their rows so that only complete observations are used |
## Not run:

prostate <- h2o.uploadFile(path = prostate_path)
var(prostate$AGE)
