Here is my code:
data <- mtcars
colnames(data) <- apply(expand.grid(c('c'),1:11),1,paste0,collapse = "")
rownames(data) <- apply(expand.grid(c('r'),1:32),1,paste0,collapse = "")
data
Here is the output of data:

If we look at the new names of data, there is a space in-between each of the column names "c 1", "c 2", ... , "c 9", and in each of the row names "r 1", "r 2", ..., "r 9". Is there a way to remove those spaces?
We may simply use paste directly, instead of looping
paste0('c', 1:11)
[1] "c1" "c2" "c3" "c4" "c5" "c6" "c7" "c8" "c9" "c10" "c11"
paste0("r", 1:32)
[1] "r1" "r2" "r3" "r4" "r5" "r6" "r7" "r8" "r9" "r10" "r11" "r12" "r13" "r14" "r15" "r16" "r17" "r18" "r19" "r20"
[21] "r21" "r22" "r23" "r24" "r25" "r26" "r27" "r28" "r29" "r30" "r31" "r32"
