Convert numeric p-values to character strings according to pre-defined formatting parameters. Additional formats may be added for required or desired reporting standards.
pvalString(p, format = c("default", "exact", "scientific"), digits = 3, ...)a numeric vector of p-values.
A character string indicating the desired format for the p-values. See Details for full descriptions.
For "exact" and "scientific"; indicates the
number of digits to precede scientific notation.
Additional arguments to be passed to format
When format = "default", p-values are formatted:
p > 0.99: "> 0.99"
0.99 > p > 0.10: Rounded to two digits
0.10 > p > 0.001: Rounded to three digits
0.001 > p: "< 0.001"
When format = "exact", the exact p-value is printed with the
number of significant digits equal to digits. P-values smaller
that 1*(10^-digits) are printed in scientific notation.
When format = "scientific", all values are printed in scientific
notation with digits digits printed before the e.
