R fitdistrplus library

[Michele Scarpa]

Hello,

hello i created a data funcion installingfitdistrplus library to get weibull distribution parameters:

fitdistrplus::mledist(input1, "weibull", lower=c(0,0))

when I force the lower parameters limit to avoid errors for distribution with smallshape or scale parameters, spotfire returns the following error eventhough it works fine in R studio with the very same library version.

TIBCO Enterprise Runtime for R returned an error: 'Error in fitdistrplus::mledist(input1, "weibull", lower = c(0, 0)) : argument is of length zero

eval(expr, envir, enclos)

eval(expr, envir, enclos)

distribution_check(input1)

fitdistrplus::mledist(input1, "weibull", lower = c(0, 0))'.

Can you check if any of input1 value is null Is it column type

Hello Khushboo,

 

 

 

there are no null in the column that is Real as Type.

 

using fitdistrplus::mledist(input1, "weibull") it works well but it is not what I am looking for.

 

Regards

Would it be possible to provide a sample dataset/dxp and expected output screenshot/records would help to narrow down the issue between TERR and R
