Hi ,
I want to know is this behavior expected and why is that ? Need some help
gender <- c("F", "M", "M", "F", "F", "M", "F", "F")

> typeof(df[[1]])
[1] "integer" > Why is this integer . *Should not it be

Hi Jeff ,
I dont think so ,
> df[[0]]
Error in .subset2(x, i, exact = exact) :
attempt to select less than one element

[1] F M M F F M F F
Levels: F M

Hi ,
I am concerned about the return value of typeof in character column in a
dataframe. I expect it to be of character ,it returns integer instead .
Thanks

Of course typeof returns integer; typeof returns the internal storage type
of an object. Fac
Sorry for the wrong interpretation. So how to avoid that ? I mean how to
forcefully make it character vector ?
This one , the character vector vector column is showing integer. May be I
am missing any point.
df
X1.3 name
11 abc
22 def
33 xyz

As indicated by Joshua, ?data.frame will show you the way:
df <- data.frame(gender, age, stringsAsFactors = FALSE)

Hello,
I think there is an inconsistency in the handling of the compact form of the
row.names attributes.
When n is the number of rows of a data.frame, the compact form is
c(NA_integer_,-n), as in:
> d <- data.frame(x=1:10)
> .Internal(inspect(d))
