Dear All, I need to separate one column which is in a format like, "can_region", into two columns like, "can", and "region". Do we have a function in R to do this? Thanks. Regards, Jin [[alternative HTML version deleted]]
Does strsplit fit what you want?

hi, all.
I am a beginner. Could you tell me how to use read.table() to read
following beams.txt file.
thanks
file content is here:
"beams" <-
structure(list(strength = c(11.14, 12.74, 13.13, 11.51, 12.38,
12.6, 11.13, 11.7, 11.02, 11.41), SpecificGravity = c(0.499,
0.558, 0.604, 0.441, 0.55, 0.528, 0.418, 0.48, 0.406, 0.467),
moisture = c(11.1, 8.9, 8.8, 8.9, 8.8, 9.9, 10.7, 10.5, 10.5,
10.7)), .Names = c("strength", "SpecificGravity",
"moisture"
), class = "data.frame", row.names = c("1", "2",
"3", "4", "5",
"6", "7", "8", "9", "10"))
Try source("beams.txt") which reads and executes the commands in
beams.txt.
It might make more sense in future to store and work with dataframes,
especially with big datasets.
