parsec (version 1.2.7)

upset: upset

Description

The function computes a boolean vector specifying which poset elements belong to the downset generated by subposet Q.

Usage

upset(z, ...)
# S3 method for cover
upset(z, ...)
# S3 method for incidence
upset(z, Q = NULL, ...)

Arguments

z

a cover or an incidence matrix, of S3 classes cover or incidence, respectively.

Q

vector specifying a subposet of the poset represented by z.

...

any of the above.

Examples

z <- getzeta(var2prof(varlen = c(2, 2, 2)))

plot(z, col = 1 + c(1, 1, 0, 0, 1, 0, 0, 0) + c(0, 0, 0, 2, 0, 0, 2, 2), lwd = 2)

Q <- c(4, 7, 8)
rownames(z)[Q]
upset(z, Q)

Q <- c("211", "112", "111")
upset(z, Q)
