Help Subject: [R] split dataframe to several dataframes in R Hi All,I have a dataframe called 'means' as shown below:iris1.csv <- iris iris2.csv <- iris names <- c("iris1.csv", "iris2.csv") dat <- mget(names) lst4 <- lapply(dat, function(x) apply(x[,-5], 2, mean)) # Build the new data frame means <- as.data.frame(do.call(rbind, lst4)) means$source <- names(lst4) means # Sepal.Length Sepal.Width Petal.Length Petal.Width isv source # iris1.csv 5.843333 3.057333 3.758 1.199333 0.3333333 iris1.csv # iris2.csv 5.843333 3.057333 3.758 1.199333 0.3333333 iris2.csvQUESTION: How can I split 'means' such that there are two files (dataframes) on my workspace:datframe 1# Sepal.Length Sepal.Width Petal.Length Petal.Width isv # iris1.csv 5.843333 3.057333 3.758 1.199333 0.3333333dataframe 2:# Sepal.Length Sepal.Width Petal.Length Petal.Width isv# iris2.csv 5.843333 3.057333 3.758 1.199333 0.3333333 Many thanks,Asong.
