R returns NULL when trying to extract P value

I am running a PGLS loop on 1,000 trees and I am trying to extract slope, standard error, and P-values from my loop. Slope and standard error are easily extracted by using data$model$coef[2] and data$sterr[2] but the p value just does not want to come out. I have tried

1)summary(result)$pvalue which gives value NULL

2)data$model$coef[2,4] which says this is out of bounds (in fact playing around I couldn't access anything outside of the first column of coefficients without receiving the same error message)

I have tried a slew of other methods that are more or less the same idea as these two and each time I either get the dreaded NULL, the occasional NA or the out of bounds error. Does anyone know what is going on? I know we typically provide the data but this seems like a menial question (although I have spent significantly more time trying to resolve this that in my actual PGLS).

I do not think it is possible directly See this (old) question. Perhaps the easiest way is to use the summary object to extract the necessary information to calculate it yourself (via a helper function)?
