    Hello Sonal,

    Will it be possible for you or SimpliLearn support team (whoever has access) to upload a Google Doc in the shared Google Drive folder with links of this community page as well along with any other important links you may share during the tenure of the class?

    With regards,
    Sujay Kolwadkar

    Hello Soanl Ma'am,
    Please have a look of code

    v8 = 1:7
    as.logical(v8)
    v10 = c(0,1,'s',-20,10+0i,F,10.6)
    t = as.integer(v10)
    as.logical(t)
    v8&t

    ------------------------------- Output ---------------------------------
    v8 = 1:7
    > as.logical(v8)[1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE> v10 = c(0,1,'s',-20,10+0i,F,10.6)> t = as.integer(v10)Warning message:NAs introduced by coercion > as.logical(t)[1] FALSE TRUE NA TRUE NA NA TRUE> v8&t[1] FALSE TRUE NA TRUE NA NA TRUE

    _______________

    why it is showing NA ? when logically comparing element to element

    Hi santhosh, this is Shilpa Madhu. You can start any self learning classes any time but I think for this I went though statistics. It really helps to understand the concepts.

    Warning message:
    `...` is not empty.
    We detected these problematic arguments:
    * `needs_dots`
    These dots only exist to allow future extensions and should be empty.
    Did you misspecify an argument?

    This message is shown on using tibble as: tbl_df(datasetname)
    Anybody has an idea why?
