Hi list,
I am looking at the data yarn in package, I don't understand what is
dimension of this data set.
I did the following:
> library(pls)
> data(yarn)
> dim(yarn)
[1] 28 3
> head(yarn)
NIR.1 NIR.2 NIR.3 NIR.4 NIR.5 NIR.6 NIR.7 NIR.8 NIR.9
NIR.10 NIR.11
1 3.06630 3.08610 3.10790 3.09720 2.99790 2.82730 2.62330 2.40390 2.19310
2.00580 1.83790
2 3.06750 3.08570 3.09580 3.06920 2.98180 2.84080 2.67600 2.50590 2.35060
2.22300 2.11920
3 3.07500 3.09660 3.09160 3.02880 2.88490 2.68850 2.47640 2.26940 2.08240
1.91950 1.77470
4 3.08280 3.09730 3.10100 3.07350 2.99130 2.87090 2.73920 2.61020 2.50000
2.42370 2.37740
5 3.10290 3.10340 3.08480 3.02280 2.89270 2.71590 2.53840 2.37640 2.23970
2.13460 2.05340
6 3.08150 3.08490 3.04870 2.93050 2.73230 2.50890 2.29440 2.09950 1.93280
1.79250 1.66930
There were 270 columns, I only copy pasted the first 11 columns. But
either way, this is NOT 3 columns.
Could anyone let me know what is wrong here?
Thanks in advance,
Mike
