Hi,
It appears that you used left double quotation marks and right double
quotation marks in your vector for characters. The first lst assignment is
copied from your post and indicates issues. I retyped with doulbe quotation
mark and went through fine with the second lst assignment. Unicode for
double quotation mark is U+0022 and for left double quotation mark U+201C
and right double quotation mark U+201D. Although they look similar but they
are not the same in unicode.
> lst <- list(c(1,2),TRUE,c(“a”,“b”,“c”))
Error: unexpected input in "lst <- list(c(1,2),TRUE,c(“"
> lst <- list(c(1,2),TRUE,c("a","b","c"))
> lst
[[1]]
[1] 1 2
[[2]]
[1] TRUE
[[3]]
[1] "a" "b" "c"
