如何在 R 中对表 1 function 中的行进行子集化？

Question

I want to make a table using the same data source and columns but creating a subset of data for one of the columns (excluding "Large").

table1::label(data$Fraction != "Large")<-"Fraction all except large"
table1::label(data$Fraction)<-"Fraction all"
table1::table1(~Fraction+
               ~Fraction
                 | Location, data = data, transpose = F)

Answer 1

Assuming that "data" is a data.frame or similar (your example is not clear there), subset your data first:

datasubset <- subset(data, data$Fraction != "Large")

Only then plug it into table1 for formatting/exporting or whatever you're doing with that.
