You should pay close attention to the definitions of the parameters
passed to the various gamma functions.
x <- rgamma(1000, 2, 2)
library(mhsmm)
qsh <- gammafit(x)$shape; qsc <- gammafit(x)$scale
> qsh
x
x 2.009260
> qsc
x
x 0.4827448

Thank you very much for the answer!
However, instead of x being some uniform values, I have real values.
Hence, if I have dat$V1 of my interest, formula should be like this:
qqmath(~ V1, data=dat, distribution=function(V1) qgamma(V1,
shape=gammafit(dat$V1)$shape, scale=gammafit(dat$V1)$scale))

Hello ALL!
Can anyone tell me how to specify qqmath() function with distribution
qgamma?
In help it is bit vague how to pass shape and scale parameters for gamma.
Take a look at the first example, which passes in the df parameter for a
t distribution.
