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