!x,deg_freedom,cumulative!!Returns the left-tailed probability of the chi-squared distribution!is the value at which you want to evaluate the distribution, a nonnegative number!is the number of degrees of freedom, a number between 1 and 10^10, excluding 10^10!is a logical value for the function to return: the cumulative distribution function = TRUE; the probability density function = FALSE!
