Someone can help me out please ? > Hi Rantony, Try this: testdat<-matrix(c(3,2,20,25,6,12,5,50,7,24,1,15,15,15,2,35),nrow=4) colnames(testdat)<-c("ABC","PQR","XYZ","MNO") library(prettyR) # make a function for 25th percentile q25<-function(x,na.rm) return(quantile(x,prob=0.25,na.rm=na.rm)) testdesc<-describe(testdat,num.desc=c("Mode","var","q25"),xname="testdat ") print(testdesc) Note that the values in the data frame "testdesc" are numeric, except for the first column, as there are text messages that no mode exists for columns ABC, PQR and XYZ. When "testdesc" is printed, it is converted to a matrix, which coerces everything to character type.
