[Rd] a possible bug in svmlight (PR#8012)

[jyzz88@gmail.com]

When I used svmlight, I got below error:

my command is:
foo <- svmlight(y~., data= myData)

the results:
Error in file(con, "r") : unable to open connection
In addition: Warning messages:
1: svm_learn not found
2: cannot open file '_model_1.txt'

> myData[1:2,]

The klaR version is 0.4-1
OS: trying on windows and Linux gives me the same error
