construct function error

[agreco92]

the function construct uses an object called rexpr at line 23 that doesn't match any other name (maybe refers to rexprs?)

Therefore when creating a SINCERA object from an expression matrix gives an error:

Error in construct(exprmatrix = exp) : object 'rexpr' not found

Hi @agreco92 how did you fix this error? I am getting it when trying to construct S4 object using matrix from SCE.

sc <- construct(exprmatrix=as.matrix(counts(pbmc)))

Hi @lmacdonald12
I don't remember the specifics exactly, but I somehow managed to create the object by explicitly stating the sample vector in the construct function, something like this:

sc = construct(exprmatrix = exp, samplevector = rep('sample1',dim(exp)[2]))

(since I only had one sample to analyse). Hope that works!

Cheers
