[notaclue]

Hi

I have a list of names and would like to shorten every name in the column eg

I Have

David Smith
Chris Brown
etc

would like

D. Smith
C. Brown
etc

Any ideas

library(tidyverse)

(t1 <- tibble(n1 =c("David Smith","Chris Brown")))
(t2 <- mutate(rowwise(t1), 
              n2=str_split(n1," ",n=Inf),
              n3=paste0(substr(n2[[1]],1,1),"."),
              n4 =paste(n3,paste0(n2[-1]))) %>%
              ungroup())

pull(t2,n4)

A somewhat shorter version, utilising regexp:

library(tidyverse)

t1 <- tibble(n1 =c("David Smith","Chris Brown"))

t2 <- t1 %>% 
  rowwise() %>% 
  mutate(n1 = str_replace(n1, "(^.).*( )", "\\1.\\2"))

t2
#> # A tibble: 2 × 1
#> # Rowwise: 
#>   n1      
#>   <chr>   
#> 1 D. Smith
#> 2 C. Brown
