Please show us the 'lapply' statement you are using. Here is a simple
case of catching an error in an lapply and continuing:
> lapply(c(1,2,-3, 4), function(x){
+ a <- try(stopifnot(x > 0)) # force an error
+ if (inherits(a, 'try-error')) return(NULL)
+ x
+ })
Error : x > 0 is not TRUE
[[1]]
[1] 1
[[2]]
[1] 2
[[3]]
NULL
[[4]]
[1] 4
