Hi,
in a way similar to names(dat), can I address a particular index of every
vector?
like [0] of all the vectors? So that I could do something like,
ints<-which(=="x")

No, the examples dont cover it...if i have
dat <- list(INT = c("1","2","3"),
NUM = c("2.34","4.56","6.78"),
INT = c("4", "5", "6"),
NUM = c("3.44"))
I need to do a which on INT[0],NUM[0],INT[0] and NUM[0]...ie the [0] index
of all the vectors...
and test if they

Not sure I follow you exactly, but you can use which() with any
logica
Hi Rajesh,
This will work, unfortunately it seems like lapply() drops the names
before it passes each element of the list which lead to my clumsy work
around using which(). I'm sure there are other ways.
dat <- list(INT = c("1","2","3"),
NUM = c("2.34","4.56","6.78"),
INT

I'm sorry. you seem to have misunderstood my data representation for input.
Here's what I have
c<-list(INT=c("1","2","3"),NUM=c("2.34","4.56","6.78"))
I need
c<-list(INT=c(1,2,3),NUM=c(2.34,4.56,6.78))

So there is one item per line and the task is to recognize the strings
"INT" and "NUM" and create variables with numeric type and
INT=c(2,3,4)
NUM=c(2.37, 4.56) # ???
I worry that is not a full description of the task if there be
more than just two variable names and if all the INTs ha
The string vector actually comes as a part of a list, and the vector is
named "int", and the numbers are strings. I then have to make it a vector
that is still called "int" and has 4,5,6 etc. the types are either integer
or numeric. The number of items in the vector is unknown.
here's an example,

But what is the right answer? And what number of items are possble

for e.g., I get the following as a string vector
"int" "4" "5" "6"
after reading the first element, I have to convert this to a integer vector

Hi,
Is it possible to convert a string vector to integer or numeric vector? In
my situation I receive data in a string vector and have to convert it based
