Summarize a continuous dependent(y) variable with three independent(x) variables.
tsum3(d, y, l, u, e=c("Mean", "SD", "N"), h=NULL, ol1="", ol2="", ou="",
rm.dup=TRUE, repl=list(c("length"), c("n")))
A data.frame of summarized values. Column names are from the levels of u
. Row names are basically from the levels of l
.
a data.frame or matrix with colnames
y variable name. a continuous variable
a vector of two x variable names to be shown on the left side. The length should be 2.
x variable name to be shown on the upper side
a vector of summarize function names
a list of two vectors of summarize function names for the first and second horizontal subgroups. If NULL
, it becomes the same as e
argument.
order of levels of 1st left side x variable
order of levels of 2nd left side x variable
order of levels of upper side x variable
if TRUE
, duplicated names of levels are specified on the first occurrence only.
list of strings to replace after summarize. The length of list should be 2, and both should have the same length.
