Comparing 'user' Internet connection from some Catalan research centers

Using the same technique seen in the old post “Comparing ping time between connections” I asked some colleges to run the following command in their research centers. ping -c 200 > ping_google.txt So, I load the multiple ping-files to create a data.frame with the icmp_seq number, the time spend per ping and the institution where the ping was promoted. ping <- lapply( files, function( file ) { dta <- read.

Comparing ping time between connections

To perform this test I ping 200 times Google from my PC at ISGlobal (running Linux Mint in a Virtual Machine) and from my laptop (running native Ubuntu). I saved the output in two TXT files with a command like the following one: ping -c 200 > ping_google_work_wifi.txt I processed both files in R to create a data.frame. pwm <- read.delim( file1, nrows = 200, skip = 1, header = FALSE, sep = " ", stringsAsFactors = FALSE ) pwm <- pwm[ , c( 6, 8 ) ] colnames( pwm ) <- c( "icmp_seq", "time" ) pwm$icmp_seq <- as.
