In moosik/snorm: Supporting function for supervised exploration of data structure

Description Usage Arguments Value See Also

This function combines eigen vectors with the metadata, creates a scatter plot (ggplot2 graphics) between two eigenvectors and colors the points by a variable present in the metadata. The metadata and the matrix of the eigen vectors are matched by row names.

1	pcScatter(eigens, metadata, pc.to.plot, variable, title = NULL)

`eigens`	a matrix with the eigen vectors
`metadata`	a data frame with the variable of interest (points color), must have row and column names
`pc.to.plot`	a numeric vector with two elements indicating which two eigen vectors should be used for a scatter plot
`variable`	a string indicating a name of the variable in the metadata by which the points of the scatter plot should be colored
`title`	string for the plot title. Default is NULL - no plot title

plot: ggplot2 plot object
eigen.meta: data frame of the metadata merged with the matrix of the eigen vectors
