Usage

data(schiz)

Format

The format is: num [1:30, 1:17] 312 272 350 286 268 328 298 356 292 308 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:17] "nonsch1" "nonsch2" "nonsch3" "nonsch4" ... A numerical matrix with individuals as columns.

Examples

data(schiz)
str(schiz)
# Making figure 18.1 in the book:
opar <- par(no.readonly=TRUE)
par( mar=c(2.0, 1,1,1))
par(mfrow=c(5,4))
for (i in 1:11) hist( log(schiz[,i]), main="", xlab="", ylab="", xlim=c(5.4, 7.5))
par( mfg=c(4, 1))
for (i in 1:6) hist( log(schiz[,11+i]), main="", xlab="", ylab="", xlim=c(5.4, 7.5))
