hello; firstly, my gratitude to all who help me to find a function that allows me to add confidence interval to my graph. in order to calculate the (1-alpha)th percentile of for exemple an F(df1,df2) distribution i do like this: v<-df(alpha,df1,df2) percentile<-qf(v,df1,df2,alpha) if it is true please alert me , and if it is not what should do then? :handshake: -- View this message in

i a have transformed my data to data frame named df with only column names(no rownames).each column represnt one sample with 3 observations (in deed nrow(df)=3, and ncol(df)=92).in order to check homoskedasticity of variance of my 92 samples i do: bartlett.test(df) it work and give me a result.but i'm afread of getting false result,knowen that a call of such function require a vector of data
