Hello,<br>
------------------------------<br>
<br>
I have been practicing with the book and it?s been great so far. However,<br>
there seems to be a problem with *Partial Least Squares Regression* in<br>
superClass() function. When I run the following code:<br>
<br>
sc <- superClass(p224r63_2011, trainData = training_2011, responseCol<br>
= "class_name", model = "pls*<br>
<br>
I get the following error:<br>
<br>
*Error: Required package is missing in addition: Warning message: package<br>
?caret? was built under R version 3.4.4.*<br>
<br>
When I first encountered this problem, I run *superClass()* using different<br>
models without *lapply ()* in order to identify where the problem was. It<br>
occurred to me that Random Forest and Support Vector Machines with radial<br>
basis kernel work as required while when I include ?model = ?pls?? it<br>
produces that error.<br>
<br>
NB: I thought maybe it was because of caret package, so I installed it but<br>
it seems it was not.<br>
<br>
Which package is missing?<br>
<br>
Thank you,<br>
<br>
Rop<br>

Hi,<br>
<br>
install.packages("pls") should do the trick.<br>
<br>
cheers,<br>
