gt.result-class {globaltest} | R Documentation |
Class "gt.result" for results of the function globaltest
Description
The class gt.result is the output of a call to
globaltest
and the input of various plotting
functions to visualize the test result.
Slots
res
:- Object of class "matrix". Test results, with a row for each element of
test.genes
, and the following columns: path.n
: length of input vector,
test.n
: number of rows in X
that matched the input vector, Q
: test statistic,
EQ
: expectation for the test statistic, seQ
: standard deviation of the test
statistic, p.val
: p value comp.p
: comparative p if sampling = TRUE
X
:- Object of class "matrix". The transformed data matrix.
Y
:- Object of class "numeric". The transformed clinical outcome vector.
test.genes
:- A list of vectors indicating the tested genes.
adjustmatrix
:- Object of class "matrix" needed to calculate the expectation
of the test statistic.
Rsquare
:- Object of class "numeric". Percentage of the variance of Y left after adjustment
for confounders or known risk factors.
model
:- Object of class "character". The model used by the test ("linear" or "logistic").
df.adjust
:- Object of class "numeric". The number of degrees of freedom used in the
adjustment of the test.
Methods
- show
- (gt.result): Summarizes the test result
- p.value
- (gt.result): Extracts the p-values.
- result
- (gt.result): Extracts the results matrix.
- geneplot
- (gt.result): Produces a plot to show the influence of individual
genes on the test result produced by
globaltest
.
- sampleplot
- (gt.result): Produces a plot to show the influence of individual
samples on the test result produced by
globaltest
.
- permutations
- (gt.result): Produces a histogram for visualization of the
permutations used in
globaltest
.
- checkerboard
- (gt.result): Produces a plot to visualize the test result
produced by
globaltest
by showing the association
between pairs of samples.
- regressionplot
- (gt.result): Produces a plot which can be used to visualize
the effect of specific samples on the test result produced by
globaltest
.
