I have the following string input:
input <-
"ACC,1.1,2.2,3.3,4.4\nACC,2.2,3,4,5\nADN,3.3,4,5\nACC,4.4,5.5,6.6,7.7\nADN,5.5,6,7\n"
Note that \n is a real line feed in the data and the numbers are all made up
and might be other values. The key is that the first number is a float, the
ACC packets are all floats and the ADN the first value is a float and the
rest are ints.
I want to turn this string into a vector of packets. I tired using grep and
regexpr without luck. I would also like to filter the packets so that I can
get a vector of just the ACC packets and another vector of just the ADN
packets.
When I tried this:
grep ("ACC", input, FALSE, FALSE, TRUE)
What I ended up with was:
[1] "ACC,1.1,2.2,3.3,4.4" "ACC,2.2,3,4,5" "ADN,3.3,4,5"
"ACC,4.4,5.5,6.6,7.7" "ADN,5.5,6,7"
What I wanted was:
[1] "ACC,1.1,2.2,3.3,4.4"
[2] "ACC,2.2,3,4,5"
[3] "ACC,4.4,5.5,6.6,7.7"
Then I wanted to put in grep ("ADN", input, FALSE, FALSE, TRUE) and get out:
[1] "ADN,3.3,4,5"
[2] "ADN,5.5,6,7"
Can someone help me figure this out?
