You can see that the paste0() function has the default separator value. Paste0() function acts just like paste function but with a default separator. Output = “John=1 and Ray=2 and John=3 and Ray=4 and John=5” Output = "a_1 and b_2 and a_3 and b_4 and a_5 and b_6 and a_7 and b_8 and a_9 and b_1 paste (c ( 'John', 'Ray' ), 1 : 5 ,sep = '=' ,collapse = ' and ' ) The separator will deal with the values which are to be placed in between the set of elements and the collapse argument will make use of specific value to concatenate the elements into single -string. Let’s see how separator and collapse arguments will work. The paste() function with both separator and collapse arguments Output = “Rita and Sam and John and Jat and Cook and Reaper” It represents the symbol or values which separate the elements in the vector. Hence here comes the collapse parameter, which is highly useful when you are dealing with the vectors. When you pass a paste argument to a vector, the separator parameter will not work. The paste() function with collapse argument The separator parameter in the paste() function will deal with the value or the symbols which are used to separate the elements, which is taken as input by the paste() function. But you can also change the separator value using the ‘sep’ parameter. The elements will be separated by a space as the default option. The syntax of the paste0() function is, paste (x ,collapse = NULL )Ī simple paste() will take multiple elements as inputs and concatenate those inputs into a single string.
