Hi Every one,
I have a dataframe "class" with "name", "sex", "age", "height", "Weight".
if i caluclate summary statistics with the below code
numSummary(class[,c("Height", "Weight")], groups=class$Name,
statistics=c("mean", "sd", "quantiles"), quantiles=c(0,
.25,.5,.75,1))
iam getting output like this
Variable: Height
mean sd 0% 25% 50% 75% 100% n
Alfred 69.0 NA 69.0 69.0 69.0 69.0 69.0 1
Alice 56.5 NA 56.5 56.5 56.5 56.5 56.5 1
Barbara 65.3 NA 65.3 65.3 65.3 65.3 65.3 1
