Perform Welch's t-test

Performs a Welch's t-test and calculates p-values between two groups.

ttest_protti(mean1, mean2, sd1, sd2, n1, n2, log_values = TRUE)

Arguments

mean1

a numeric vector that contains the means of group1.

mean2

a numeric vector that contains the means of group2.

sd1

a numeric vector that contains the standard deviations of group1.

sd2

a numeric vector that contains the standard deviations of group2.

n1

a numeric vector that contains the number of replicates used for the calculation of each mean and standard deviation of group1.

n2

a numeric vector that contains the number of replicates used for the calculation of each mean and standard deviation of group2.

log_values

a logical value that indicates if values are log transformed. This determines how fold changes are calculated. Default is log_values = TRUE.

Value

A data frame that contains the calculated differences of means, standard error, t statistic and p-values.

Examples

ttest_protti(
  mean1 = 10,
  mean2 = 15.5,
  sd1 = 1,
  sd2 = 0.5,
  n1 = 3,
  n2 = 3
