Download Batymetry and Glacial Aulfage again and again

Question

when I plot a map using ggspatial and ggOceanMaps, I always get the message when I restart the code (i.e. with reset of the environment):

Cannot find files:

C:\Users\AppData\Local\Temp\Rtmpo1nDLv\arctic_land.rda,
C:\Users\AppData\Local\Temp\Rtmpo1nDLv\arctic_glacier.rda,
C:\Users\AppData\Local\Temp\Rtmpo1nDLv\dd_rbathy_cont.rda.

Do you want download them now?

1: Yes

2: No

selection: 1

And I have to download everything again (I don't know if I fill the memory of my computer piece by piece). Can I avoid this or will the old data be deleted when I download it?

My code:

library(ggOceanMaps)
library(readxl)
library(ggspatial)
library(dplyr)

    )), row.names = c(NA, -6L), class = c("tbl_df", "tbl", "data.frame"
))

data <- bind_rows(list(data_a,data_b), .id="data_source")
