imputePairs {mclust} | R Documentation |
Creates a scatter plot for each pair of variables in given data, allowing display of imputations for missing values in different colors and symbols than nonmissing values.
imputePairs(x, impx, symbols = c(16,1), colors = c("black", "red"), labels, panel = points, ..., lower.panel = panel, upper.panel = panel, diag.panel = NULL, text.panel = textPanel, label.pos = 0.5 + has.diag/3, cex.labels = NULL, font.labels = 1, row1attop = TRUE, gap = 1)
x |
A numeric vector, matrix, or data frame of observations containing missing values. Categorical variables are not allowed. If a matrix or data frame, rows correspond to observations and columns correspond to variables. |
impx |
The dataset x with missing values imputed.
|
symbols |
Either an integer or character vector assigning plotting symbols to the nonmissing data and impued values, respectively. The default is a closed circle for the nonmissing data and an open circle for the imputed values. |
colors |
Either an integer or character vector assigning colors to the nonmissing data and impued values, respectively. The default is black for the nonmissing data and red for the imputed values. |
