How do I prevent a for loop is overwriting my results - r

Question

I would like to scrape all the seasons from 2003-2004 to 2019-2020 of the Dutch football league including the 34 playing rounds (I am using this website https://www.voetbal.com/wedstrijdgegevens/ned-eredivisie-2003-2004-spieltag/). As you can see in my code it's only showing me de results of de last season. I think it's overwriting the other seasons. What am I doing wrong? What do I have to add to my code? Can anybody help me?
Here is the code I use:
library(tidyverse)
library(dplyr)
library(ggplot2)
library(caret)
library(rvest)
library(devtools)
library(httr)
library(tidyr)
library(tibble)
library(xml2)
library(tidyr)
library(stringr)
url <- sprintf("https://www.voetbal.com/wedstrijdgegevens/ned-eredivisie-%d-%d-spieltag/", 2003:2019, 2004:2020)
basis<-function(url){
website <- read_html(url)
Sys.sleep(2)
datum <- website %>%
html_nodes(".data .standard_tabelle td[nowrap]:nth-of-type(1)") %>%
html_text()
tijdstip <- website %>%
html_nodes(".data .standard_tabelle td[nowrap]:nth-of-type(2)") %>%
html_text()
thuisclub <- website %>%
html_nodes(".data .standard_tabelle [align='right'] a") %>%
html_text()
uitclub <- website %>%
html_nodes(".standard_tabelle td:nth-of-type(5) a") %>%
html_text()
uitslag <- website %>%
html_nodes(".data .standard_tabelle td[nowrap]:nth-of-type(6)") %>%
html_text()
return(tibble(datum=datum, tijdstip=tijdstip, thuisclub=thuisclub, uitclub=uitclub, uitslag=uitslag))
}
overige_seizoenen<-function(url){
for (i in 1:17){
list_of_pages<-str_c(url[[i]], 1:34)
table <-list_of_pages%>%
map(basis)%>%
bind_rows()
}
return(table)
}
jochem <- overige_seizoenen(url)
```

I suspect there is an error in the for loop. In R, if you want a loop to iterate from element 1 to 10, you can't just say for (i in 10), you must clarify it as for (i in 1:10). So try this loop now:
for (i in 1:seizoenen){
list_of_pages<-str_c(url[[i]], 1:34)
table <-list_of_pages%>%
map(basis)%>%
bind_rows()
}
return(table)
}
