Plot parameters correlations

Returns selected parameters correlations in the form of either a matrix, a data frame or a plot.

plot_parameters_correlations(run, parameters = NULL, type = "heatmap",
  correlation_method = NULL, baseline_only = TRUE, auto_order = TRUE,
  smoothing_method = NULL, smoothing_se = TRUE, fixed_ratio = TRUE,
  auto_legend = TRUE)

Arguments

run	pmxploit NONMEM run object.
parameters	character vector of parameters names. Default is NULL, returning all individual parameters (random and post-hoc).#'
type	character. Type of plot. One of heatmap or scatterplot.
correlation_method	a character string indicating which correlation coefficient (or covariance) is to be computed. One of "pearson" (default), "kendall", or "spearman": can be abbreviated. If type = "scatterplot", "pearson" method will be used.
baseline_only	logical. Consider only the baseline (= first) values of the subjects. Default is TRUE.
auto_order	logical. If type = "heatmap", auto-orders the matrix with respect to the distances between values. Default is TRUE.
smoothing_method	character. If type = "scatterplot", corresponds to a ggplot2 smoothing method.
smoothing_se	logical. Display confidence interval around smooth?
fixed_ratio	logical. If type = "heatmap", plot scaled to a 1:1 ratio. Default is TRUE.
auto_legend	logical. When TRUE (default), default pmxploit plotting options are applied (title, labels, axis...).

Value

A ggplot2 object.
