ss.ceDiag | R Documentation |
Represents a Cause and Effect Diagram by cause group.
ss.ceDiag(
effect,
causes.gr,
causes,
main = "Six Sigma Cause-and-effect Diagram",
sub,
ss.col = c("#666666", "#BBBBBB", "#CCCCCC", "#DDDDDD", "#EEEEEE", "#FFFFFF", "#000000",
"#000000")
)
effect |
A short character string that represents the effect we want to analyse. |
causes.gr |
A vector of characters that represents the causes groups. |
causes |
A vector with lists that represents the individual causes for each |
main |
Main title for the diagram |
sub |
Subtitle for the diagram (recommended the Six Sigma project name) |
ss.col |
A vector of colors for a personalized drawing. At least five colors, sorted by descendant intensity |
The default value for ss.col is c("#666666", "#BBBBBB", "#CCCCCC", "#DDDDDD", "#EEEEEE", "#FFFFFF", "#000000", "#000000"), a grayscale style. You can pass any accepted colour string.
A drawing of the causes and effect with "fish-bone" shape
The cause and effect diagram is also known as "Ishikawa diagram", and has been widely used in Quality Management. It is one of the Seven Basic Tools of Quality.
