sumz.tab | R Documentation |
This function populates the sumz.cp table using the resuls from function 'ivzsums' and, if 'boot'=TRUE, calls 'ivsums.f' to compute ivz sums filtered by pure and reliable taxa.

ivz,

)
ivzScores |
The product of the 'getivz' function. A data matrix comprised of four submatrices including group membership, z scores, IndVals, and p values. |
ivz |
The product of the 'ivzsums' function. A data matrix comprised of two parallel vectors of sum(z-) and sum(z+) scores. |
srtEnv |
A sorted version of the environmental gradient. |
sppmax |
The taxon-specific summary output table from TITAN, passed to 'ivzsums.f'. |
maxSumz |
A vector of sum(z) maxima across bootstrap replicates. |
maxFsumz |
A vector of sum(z) maxima filtered by pure and reliable taxa across bootstrap replicates. |
minSplt |
The minimum split size used to partition the environmental gradient. The default is to use the argument specified by the original TITAN function call. |
boot |
A logical indicating whether the bootstrap procedure should be implemented. The default is to use the argument specified by the original TITAN function call. |
The function locates the env values of sum(z) maxima, then if 'boot'=TRUE, locates the the env value of the filtered sum(z) and provides bootstrap quantiles of both filtered and unfiltered distributions.
A list with two objects:
A second summary output table from TITAN to accompany 'sppmax'.
The product of the 'ivzsums.f' function. A data matrix comprised of two parallel vectors of filtered sum(z-) and sum(z+) scores.
