R "requires numeric/complex matrix/vector arguments" -


i intend multiplicate 2 matrices. math pretty basic.

inputa represents 8760x175 matrix , inputb 175x1 matrix (rows x columns). there should no problem math...

however, if used as.matrix command save inputb, inputb still saved character. transposing , re-transposing doesn't either. i'm pretty clueless right now, simple on paper, can't work in r studio

 inputa <- as.matrix(input_de_2014_bundeslaender_xml_ee_alpha[-1:-4,-1:-3])  inputb <- as.matrix(input_de_2014_bundeslaender_xml_ee_cap[-1:-2])  inputb <- inputb[,-2:-4]  inputb <- inputb[-1,]  inputb <- inputb[,-2]  newmatr <- inputa %*% inputb
