Hi all,
I have an Nx2 array, where the first column contains the timestamps
and the
second column contains the corresponding data.
second | ts
--------| --
14:25:00| 18
14:25:02| 14
14:25:04| 11
14:25:06| 4
14:25:08| 24
14:25:10| 13
14:25:12| 12
14:25:14| 6
14:25:16| 21
14:25:18| 37
14:25:20| 21
14:25:22| 9
Since I don't know how to do this in R yet, please allow me to show
data in
Matlab:
> tz <- read.table(textConnection("second | ts
+ 14:25:00| 18
+ 14:25:02| 14
+ 14:25:04| 11
+ 14:25:06| 4
+ 14:25:08| 24
+ 14:25:10| 13
+ 14:25:12| 12
+ 14:25:14| 6
+ 14:25:16| 21
+ 14:25:18| 37
+ 14:25:20| 21
+ 14:25:22| 9"), header=TRUE, sep="|")
In Matlab, the first column becomes:
0.600694444496185
0.600752314785495
0.600810185191222
0.600868055596948
0.600925925886258
0.600983796291985
0.601041666697711
0.601099536987022
0.601157407392748
How do I plot such data with X-axis showing the timestamps
(seconds) and the
Y-axis showing the data?
# Should have included the package call and perhaps
install.packages("zoo)
require(zoo)
> plot (zoo(tz[,2], order.by=tz[,1]) )
