[R] Error when I attempt to create a list or a data frame

[JS Huang]

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"
