Reading data for the AALTD’16 Time Series Classification Contest: R

In the following, we assume that you downloaded the files:

• train.h5
• test_task1.h5

and copied them in your R working folder.

We also assume that you have R installed with h5 package.

Start R, and then:

library(h5)
fp <- h5file("train.h5", "r")
x = fp["time_series"]
y = fp["labels"]

dim(x)

## [1] 180  51  24

dim(y)

## [1] 180

Now, let’s have a look at test data:

fp <- h5file("test_task1.h5", "r")
x = fp["time_series"]

dim(x)

## [1] 180  51  24

Of course, something is missing:

y = fp["labels"]
