Hello Rlisters!
In my codes, I need to import a matrix:
v <- read.table("/home/tiago/matrix.txt", header=FALSE)
v<-as.matrix(v)
v
V1 V2 V3 V4 V5 V6
[1,] 1.00000000 -0.89847480 -0.73929292 -0.99055335 -0.04514469 0.04056137
[2,] -0.89847480 1.00000000 0.95986852 0.82978466 0.04056137 -0.04514469
[3,] -0.73929292 0.95986852 1.00000000 0.63996937 0.03337515 -0.04333297
[4,] -0.99055335 0.82978466 0.63996937 1.00000000 0.04471823 -0.03746038
[5,] -0.04514469 0.04056137 0.03337515 0.04471823 1.00000000 -0.89847480
[6,] 0.04056137 -0.04514469 -0.04333297 -0.03746038 -0.89847480 1.00000000
[7,] -0.60519045 0.67357531 0.64654374 0.55892246 -0.06244832 0.06950480
V7
[1,] -0.60519045
[2,] 0.67357531
[3,] 0.64654374
[4,] 0.55892246
[5,] -0.06244832
[6,] 0.06950480
[7,] 1.00000000
However, I keep getting the same error after loading that matrix:
`v' is not a covariance matrix
Nonetheless, if I input the matrix directly, there is no error:

How can one import the data correctly?
I could not figure it out.
Thanks in advance.
