doANOVA {ABarray} | R Documentation |
If only one factor is provided in parameter, one way ANOVA is performed. If two factors are provided, two way ANOVA is performed.
doANOVA(eset, group1, group2, snThresh = 3, detectSample = 0.5)
eset |
An ExpressionSet object |
group1 |
factor name or labels to test on. If dataf is an exprSet object, either name or labels can be used. If dataf is an expression matrix, lables should be used. |
group2 |
factor name or labels to test on |
snThresh |
Using probes detectable for ANOVA analysis, default S/N value is 3 or more to be considered detectable |
detectSample |
The percentage of samples the probe is detected in order to be considered in ANOVA analysis |
At least one group should be provided. If exprSet object is used, group1 or group2 is the name of the sampleGroup defined in experiment design file. If labels are to be used, they can be either numeric or text, e.g., c(1,1,2,2,3,3) or c("treat1", "treat1", "treat2", "treat2", "treat3", "treat3").
If the probe is detectable in 50% (default) or more samples in any one of the subgroup, it is included in the ANOVA analysis.
a vector if one way ANOVA; a matrix if two way ANOVA
