r - Creating a list for search query from column using dbhydroR package -

i trying create list can copy search query function data.frame column. output below code in format of :

‘c-484,''f-409,''s-18a,''g-850,''pb-632,'...etc. 

but need read

'c-484','f-409','s-18a','g-850','pb-632', ...etc. 

there 1,974 variables. how can switch placement of last quote around each variable comma?

inactivestations <- read.csv("inactive_wells.csv",header=true)  #subset , make data.frame station (station names) allstations_inactive <- inactivestations['station']   #not separated in way can copied query list(allstations_inactive$station)   #separated commas , has quotes around each variable commas inside quotes test<-paste0(allstations_inactive$station, collapse="''",sep=",")   ##separated commas , has quotes around each variable commas inside quotes test1<-paste0(allstations_inactive$station, sep=",",collapse="''")  

thank in advance

this approach works:

input <- c("c-484", "f-409", "s-18a", "g-850", "pb-632") output <- paste0("'", input, "'", collapse = ",") # cat(output) # 'c-484','f-409','s-18a','g-850','pb-632' 

so in specific case becomes:

test1 <- paste0("'", allstations_inactive$station, "'", collapse = ",")
