makeShapeDiffCon {cosmo} | R Documentation |
This function constructs a texttt{shapeDiffCon} object representing a constraint on the unknown position weight matrix that requires the the difference between the information content at the edge of one interval and the information content at the edge of another interval to be bounded betwene given bounds. This constraint may only be applied to intervals that already have a shape constraint.
makeShapeDiffCon(int1, int2, lower, upper)
int1 |
character the location of the first information
content of interest. This is specified as the number of the interval
followed by the letter a or b depending on whether the
left or right edge of the interval is desired. |
int2 |
character the location of the second information
content of interest. This is specified as the number of the interval
followed by the letter a or b depending on whether the
left or right edge of the interval is desired. |
lower |
numeric the lower bound on the difference in
information contents. |
upper |
numeric the upper bound on the difference in
information contents. |
An object of class texttt{shapeDiffCon}.
