Re: [R] Conditional Loop For Data Frame Columns

Hi Dave, Thanks for your response! I'm new at R, and I'm afraid I'm not sure what you mean by: ?lapply ?"[" ?order Were these suggestions for other commands to try? If so, can you be more specific? I apologize for being clueless :) Secondly, you're right that the script I have now leaves me

[R] Conditional Loop For Data Frame Columns

Hi, I am trying to create a script that will evaluate each column of a data frame, regardless of # columns, using some function and sorting the results by an index vector: #upload data (112 rows x 73 columns) SD <- read.csv("/Users/johnjacob/Desktop/StudentsData_RInput.csv", header=TRUE) #assign

Re: [R] Length of data.frame column

I have a related question...I have a data frame similar with 74 rows that I created with "header=TRUE", but when I try to coerce one of the data frame columns into a vector, it shows up as having length 1, even though when I print it, it shows 74 elements: > VAL <- c(DailyDiary[1]) > VAL > [1] 3 3
