Hello All,
I use Cygwin ( unix on windows) heavily for all my text data processing.
Also use Cygwin inbuilt *R* to do numerical processing.
*My aim is to integrate R and unix commands to avoid heavy memory usage that
R takes normally.*
I can run many unix commands using system("some unix command or sh script.sh
or even R file itself ") inside R.
But, When I tried to run the command *awk '{print "Hello"$1}' infile.txt* to
prefix "Hello" to my first column of file infile.txt, like below in *R *
*system(" awk '{print "Hello"$1}' infile.txt") *, I am getting the below
error,
*Error: unexpected symbol in "system("awk '{print "Hello"*
I tried even like *system('awk '{print "Hello"$1}' infile.txt')*, but still
the same error.
This particular error is hampering my entire work, other wise I found this
is excellent way processing the text files at the same time reading back and
forth file outputs from R to unix and vice versa.
Can some one give me provide some solution to this problem ??
