R help - Nov 2020 - How to pass a character string with a hyphen

R-Help

 

How does one pass a character string containing a hyphen? I have a function
that accesses an api if I hard code the object, for example

 

key_key <- "xxxx-yyyy" 

 

it works but when I pass the key  code to the function (say something like
key_code <- code_input)  it returns only xxxx. So R is seeing a string with
a negative operator I'm assuming

tmp <- function(s) {
  return(str(s))
}
key <- "xxxx-yyyy"
tmp(key)

#  chr "xxxx-yyyy"

... works for me.

Reprex?

Cheers,

Hi everyone.  I have a dataframe that is a collection of Vendor IDs  
plus a bank account number for each vendor. I'm trying to find a way  
to count the number of duplicate bank accounts that occur in more than  
one unique Vendor_ID, and then assign the count value for each row in  
the dataframe in a new variable.

I can do a count of bank accounts that occur within the same vendor  
using dplyr and group_by and count, but I can't figure out a way to  
count duplicates among multiple Vendor_IDs.


Dataframe example code:


#Create a sample data frame:

set.seed(1)

Data <- data.frame(Vendor_ID = sample(1:10000), Bank_Account_ID =  
sample(1:10000))




Thanks in advance for any help.

Yes in that case it works as you have assigned a character string to key. My
problem is I'm taking a string input from a shiny app and when I run the
function it only sees xxxx.  How to assign xxxx-yyyy to a character string.

Hi,

You might want to look at ?shQuote, which wraps text in single quotes, if the
source text does not include them, or double quotes otherwise, as might be used
in a shell setting, where you are passing arguments that may have spaces or
other characters that may be evaluated.

My guess is that the API that you are passing the character vector to may be
parsing/evaluating the '-' and only seeing the first part of the passed
value.

So, for example:
> shQuote("xxxx-yyyy")
[1] "'xxxx-yyyy'"


See if that works.

Regards,

Marc Schwartz

Strip the left characters and strip the right characters into their own
variables using one of the methods that can do that.  Then pass it using
something like paste(left, "-", right).
