Hi,
Trying to give an example here.
Say, I have read in a .csv file using read.csv (), and the file contains
the following info.
Names Col x Col y Col z
rowName1 A E H
rowName2 B F I
rowName3 C G J
rowName4 D K
Now, this is what is required:
1. Combine/stack/join contents from -
a) multiple rows into one column.
That is:
A
E
H
B
F
I
C
G
J
D
K
b) multiple columns into one row.
A B C D E F G H I J K
2. Stack contents from
A) multiple columns into one column.
A
B
C
D
E
F
G
H
I
J
K
B) Multiple rows into one row.
A E H B F I C G J D
Thank you.
Cheers,
Santana
