In marchtaylor/sinkr: Collection of functions with emphasis in multivariate data analysis

Return symbols for corresponding p-values

Description

Return symbols for corresponding p-values

Usage

starSym(
  x,
  breaks = c(0, 0.001, 0.01, 0.05, 0.1, 1),
  symbols = c("***", "**", "*", ".", "")
)

Arguments

x	numeric vector of p-values
breaks	numeric vector of breaks (passed to cut)
symbols	character vector of text output corresponding to cut levels

Value

character vector

Examples

ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group <- gl(2, 10, 20, labels = c("Ctl","Trt"))
weight <- c(ctl, trt)
lm.D9 <- lm(weight ~ group)
summary(lm.D9) # summary table shows stars for signifcance levels
Pvals <- summary(lm.D9)[[4]][,4] # extract p-values
starSym(x = Pvals) # reproduce stars
