Description Objects from the Class Slots Methods References See Also Examples
The CoverageObj
class is used for the storage of coverage tests results.
Objects can be created by calls of the
form new("CoverageObj", ...)
or, more commonly, via the
coverage
function.
NumPerms
:The number of permutations used if a permutation test was performed.
DistExp
:The exponent used in calculation of distances.
NumGrps
:The number of groups in the input data.
GpSizes
:A vector of length NumGrps
specifying group sizes.
inputData
:A data.frame
used for the analysis. The first column is the group (if supplied) and the second is the variable for which the analysis was performed.
ObsDelta
:The observed coverage statistic.
VarDelta
:The variance of the coverage statistic estimated using resampling.
ExpectDelta
:The expected value of the coverage statistic.
DeltaSkew
:The standard deviation of the variance of the coverage statistic.
Z_value
:The observed standardized coverage statistic.
Skt
:The skewness of observed coverage statistic.
P_value
:The Pearson Type III probability of a larger or equal coverage statistic.
PZ
:The resampled probability of a larger or equal coverage statistic.
NumObs
:The total number of observations used in the analysis.
PermVals
:If save.test=TRUE
was specified this vector will hold resampled test statistic values.
exact
:A logical value indicating whether an exact test was performed.
group.names
:The names of the groups used in the analysis.
Call
:The original function call.
signature(x = "CoverageObj")
: Prints a terse summary of the Coverage test.
signature(x = "CoverageObj")
: Extracts the Pearson type III p-value. See pvalue
.
signature(x = "CoverageObj")
: Extracts the Monte Carlo resampled test statistic values. See ResampVals
.
signature(object = "CoverageObj")
: Same as print. See print
.
signature(object = "CoverageObj")
: Prints a detailed summary of the Coverage test.
