Hi all,I have a list that has the following fields. $`80` [1] "Error in if (fitcass1[[2]] == \"Error\") { : \n Fehlender Wert, wo TRUE/FALSE nötig ist\n" attr(,"class") [1] "try-error" attr(,"condition") <simpleError in if (fitcass1[[2]] == "Error") { print(sprintf("error at fitting gamma distribution with %s periods. Mean %f %f Sd %f %f", flag, mean1, mean2, sd1, sd2))} else { return(fitcass1)}: Fehlender Wert, wo TRUE/FALSE nötig ist>
$`81` [1] 0 $`9` [1] 0 $`79` $parameters pi mu sigma 1 0.9996796725 1.654832 127.6542 2 0.0003203275 17183.001125 302.8063 $se pi.se mu.se sigma.se 1 2.113882e-05 0.1439152 14.22274 2 2.113882e-05 38.3582148 NaN $distribution [1] "gamma" and so one. The content of each first level sublist are never the same. I want for each first-level sublist my list has to check fast that the current element , lets say the 79th has the $parameters.then I would keep only the numbers from the sublists that have this $parameters inside them and skip all the rest. I tried something like exists(Mylist[[i]]$parameters) but it does not workI also tried the is.numeric(Mylist[[i]]$parameters)) but this line fails when the current sublist does not contain the $parameters field. Can you please help me sort this out?
