Hi
I would like to do neural netowrk analysis on my data. It look like this:
drug param1 param2 param3 param4 param5 class
A 111 15 125 40 0.5 1
B 347 13 280 55 3 2
C 335 9 119 89 -40 1
D 477 37 75 2 0 1
E 863 24 180 10 5 2
F 737 28 150 15 6 2
G 390 63 167 12 0 3
H 209 93 200 48 45 3
I 376 72 201 45 -60 3
J 262 16 205 49 25 3
K 273 39 267 53 11 1
L 192 33 164 19 15 2
M 282 2 213 86 30 1
N 111 11 198 68 -21 1
O 387 20 143 12 16 2
P 674 15 78 -20 -17 2
R 734 54 140 24 7 2
S 272 46 159 57 28 2
T 245 37 90 6 31 2
I have entered the code below:
nn <- neuralnet(
+ class~param1+param2+param3+param4+param5+param5,
+ data=mydata, hidden=2, err.fct="ce",
+ linear.output=FALSE)
However the error appeared:
Error in model.frame.default(formula.reverse, data) :
object is not a matrix
I changed the data frame to matrix:
mydata.mat=as.matrix(mydata)
but still the same error appears...
How can I fix this ? I would be very grateful for your help !
