Dear R project team
I used the function of "matrix" as follows:
matrix(c(1:3030), 10.1/0.1)
However, in the function, matrix, 10.1/0.1 was regarded as 100 not as 101.
Therefore, a warning message appeared.
On the other hand, matrix(c(1:3030), 101) or matrix(c(1:3030), 10.1*10) was
OK. Of course, simply, 10.1/0.1 was successfully calculated. However,
In the "matrix" environment, 10.1/0.1 was calculated as 100.
Would you give me some answers?
Sincerely
