Continuous Information

Description

Summarization of the continuous information.

Usage

continuous.test (name,
                 x,    
                 y,
                 digits = 3,
                 scientific = FALSE, 
                 range = c("IQR","95%CI"), 
                 logchange = FALSE,
                 pos=2, 
                 method=c("non-parametric","parametric"),
                 total.column=FALSE, ...) 

Arguments

name	the name of the feature.
x	the information to summarize.
y	the classification of the cohort.
digits	how many significant digits are to be used.
scientific	either a logical specifying whether result should be encoded in scientific format.
range	the range to be visualized.
logchange	either a logical specifying whether log2 of fold change should be visualized.
pos	a value indicating the position of range to be visualized. 1 for column, 2 for row.
method	a character string indicating which test method is to be computed. "non-parametric" (default), or "parametric".
total.column	option to visualize the total (by default = "FALSE")
...	further arguments to be passed to or from methods.

Value

The function returns a table with the summarized information and the relative p-value. For non-parametric method, if the number of group is equal to two, the p-value is computed using the Wilcoxon rank-sum test, Kruskal-Wallis test otherwise. For parametric method, if the number of group is equal to two, the p-value is computed using the Student's t-Test, ANOVA one-way otherwise.
