Creating data frame from individual files
Dear Group:
I have 72 files (.txt).
Each file has 2 columns and column 1 is always identical for all 70 files.
Each file has 90,799 rows and is standard across all files.
I want to create a matrix 40(rows) x 70 columns.
I tried :
temp = list.files(pattern="*.txt")
named.list <- lapply(temp, read.delim)
library(data.table)
files.matrix <-rbindlist(named.list)

medians on data frame with duplicated rows
Dear list:
I have a data frame with student name, class he attended and marks for
subjects he attended.
Students took second exam if they performed badly in their first attempt. I
want to consider the test scores where they obtain highest median.
there are 6 classes. As a sample case, I will consider only classes A, B
and C.
For class A, Student Raj took first exam and he did not score well.
