mlayerHVT | R Documentation |
Predict which cell and what level each point in the test dataset belongs to
mlayerHVT( data, hvt_mapA, hvt_mapB, hvt_mapC, mad.threshold = 0.2, normalize = T, distance_metric = "L1_Norm", error_metric = "max", child.level = 1, line.width = c(0.6, 0.4, 0.2), color.vec = c("#141B41", "#6369D1", "#D8D2E1"), yVar = NULL, ... )
data |
Data Frame. A dataframe containing test dataset. The dataframe should have atleast one variable used while training. The variables from this dataset can also be used to overlay as heatmap |
hvt_mapA |
A list of hvt.results.model obtained from HVT function while performing hierarchical vector quantization on train data |
hvt_mapB |
A list of removed outlier rows using removedOutliers function |
hvt_mapC |
A list of hvt.results.model obtained from HVT function while performing hierarchical vector quantization on train data without outlier(s) |
mad.threshold |
A numeric values indicating the permissible Mean Absolute Deviation |
normalize |
Logical. A logical value indicating if the columns in your dataset should be normalized. Default value is TRUE. |
distance_metric |
character. The distance metric can be 'Euclidean" or "Manhattan". Euclidean is selected by default. |
error_metric |
character. The error metric can be "mean" or "max". mean is selected by default |
child.level |
A number indicating the level for which the heat map is to be plotted.(Only used if hmap.cols is not NULL) |
line.width |
Vector. A line width vector |
color.vec |
Vector. A color vector |
yVar |
character. Name of the dependent variable(s) |
... |
color.vec and line.width can be passed from here |
