The output file is stored in the working directory of our R programming environment. For example: #To print the details of people having salary between 30000 and 40000 and store the results in a new file per.sal <- subset(read.data, empsalary >= "30000" & empsalary <=...
x[1,3]<-7# Try to replace value# Error in x[1, 3] <- 7 : incorrect number of subscripts on matrix Unfortunately, the RStudio console returns the error message “incorrect number of subscripts on matrix”. The reason for this is that we have specified a two-dimensional subset of a ...
Of course, sometimes it takes a while to figure out how to do this. Please read for a great R matrix lookup problem and solution. In R we can specify operations over vectors. For arithmetic this is easy, but some more complex operations you “need to know the trick.” Patrick Freeman ...

Learn about factor analysis - a simple way to condense the data in many variables into a just a few variables.
Here is an example: let A be 6x6 matrix. I want to find a zero between rows 1 and 3, and columns 1 and 3. I tried q = (find(A(1:3,1:3) == 0) The answer I get is an array of 1 and 0, giving me an index of each 0 in terms of ...
matrix with probability columns for all possible classes). It is a great convenience to wrap these differences (and differences in training control, such as table versus function interface, tolerance/intolerance of boolean/factor/character/numeric target class labels, and more). An example of such ...
