Format P-Values
Description
This function formats p-values with specified precision. P-values smaller than 0.001 are formatted as "<0.001".
Usage
printp(pv, my.digit = 3)
Arguments
pv |
A numeric value representing a p-value. |
my.digit |
Integer; the number of decimal places to use (default is 3). |
Value
A character string representing the formatted p-value. The function ensures that the returned string is formatted according to the specified number of decimal places ('my.digit'). For p-values smaller than 0.001, the function returns "<0.001" to indicate statistical significance at a high level. This formatting helps in distinguishing between different levels of statistical significance and can be particularly useful in reporting the results of statistical tests. The format "0.000" is avoided to provide a clear indication of very small p-values, enhancing the interpretability of statistical outputs. For example, a return value of "<0.001" suggests a very strong evidence against the null hypothesis, whereas a value of "0.045" formatted with 'my.digit=3' suggests a weaker, but still significant, evidence at the 0.05 level.
Examples
printp(0.000234)
printp(0.00456, my.digit = 2)
