Hi,
One useful case is when data is sent in an email. For instance:
T1 T2 T3
-0.24 -0.26 -0.67
-1.58 0.04 0.14
-1.21 1.55 -0.45
0.31 0.48 -1.39
One could read it in via
con <- textConnection("
T1 T2 T3
-0.24 -0.26 -0.67
-1.58 0.04 0.14
-1.21 1.55 -0.45
0.31 0.48 -1.39")
read.table(con, header = TRUE)
Often a text file can be read in directly with read.table() and the
appropriate delimiter (e.g., sep = "\t" for tab, "," for comma, etc.).
Do you have a particular problem you are trying to solve or an
application of textConnection() you are interested in?
Cheers,
Josh
