Odp: Error in matrix, not ordered vectors or numerical value, and SIAR.
Hi
Help! model1 <- siarmcmcdirichletv4(data, source, tef, concdep=0, 500000,
50000)
Error in matrix(1, ncol = (numsources + numiso) * numgroups, nrow = (siardata$iterations - : invalid 'ncol' value (too large or NA) In addition: Warning message: In Ops.ordered((numsources + numiso), numgroups) : '*' is not meaningful for ordered factors Previous message, but more problems:
Maybe it is time to consult manual and help page for the function you use. For your convenience I coppied it below. I do not use the package so only few comments siarmcmcdirichletv4(data, sources, corrections = 0, concdep = 0, iterations=200000, burnin=50000, howmany=Arguments data A matrix with each food source as a seperate row and each isotope as a seperate column. ^^^^^^^^^^^^^^^^^ most probably a numeric matrix sources A matrix containing the mean and standard deviations of the fractionated correction values for each of the isotopes. Also allows corrections = 0 for pre-corrected data. ^^^^^^^^^^^^^^^^^ again a matrix (numeric) corrections A matrix containing the mean and standard deviations of the fractional correction values for each of the isotopes. Also allows corrections = 0 for pre-corrected data. ^^^^^^^^^^^^^^^^^^ and for the third time a numeric matrix Only you know what are your data, sources and tef objects which you feed to the function. Why not to follow posting guide and uncover it to us, poor helpers. Regards Petr
The data set has 101 values, what can I use instead of letters?
Why do you need to use letters? AFAIK this was only illustration what could be root of the error message. If the function requires ordered factor you can use your.ordered.factor <- ordered(your.unordered.factor) I do not remember original mail but to get rid of error message, the function probably needs as an input ordered factor or numeric values.
You
shall consult help page for this function which option is valid. as.numeric comes back as NA for the pond dataset (A3, A5, A7, B3, B7,
C2)
Cannot use ordered factor as * function does not work for this. ? And is needed to run the model (see below). ANYONE know max length for dataset in SIAR? NOW getting following error: model1 <- siarmcmcdirichletv4(data, source, tef, concdep=0, 500000,
50000)
Error in matrix(1, ncol = (numsources + numiso) * numgroups, nrow = (siardata$iterations - : invalid 'ncol' value (too large or NA) In addition: Warning message: In Ops.ordered((numsources + numiso), numgroups) : '*' is not meaningful for ordered factors Matrix 1 has only 6 vectors in column 1.
