Split based on median

[mandosch]

Hello, I am trying to split my dataframe into two different ones. I would like to create one with "high score" and the other with "low score". The cutoff value should be based one the median of a continuous variable.

Can someone help me with the code?

e.g.

data_high <- split(data,data$variable)

but how can I define the cutoff value?

Thanks in advance.

Here are a couple of ways to split the data frame using data I invented.

#Make a data frame
DF <-  data.frame(Name = LETTERS[1:20], Value = rnorm(20))

#Calculate median value
MedianValue <- median(DF$Value)

#Method 1
HighDF <- DF[DF$Value > MedianValue,]
LowDF <- DF[DF$Value <= MedianValue,]

#Method2
library(dplyr)
HighDF <- filter(DF, Value <= MedianValue)
LowDF <- filter(DF, Value > MedianValue)

Thanks a lot!! Actually easier than expected...saved a lot of time.
