Hi
I created a new table by extracting only certain rows of table, but the row
numbers in my new table correspond to those from the original table. Is there a
way to reset the row numbers in my new table so that they start from one? like
below:
my table:
COL1 COL2
17 v 45
18 b
Nina, these are not row NUMBERS, but row NAMES. Numbers are actually
reset, they always start with 1 and they are continuous. Just try
doing
T[1,]
on your table. If you want to reset row names, you can do this:
rownames(T) - seq(length=nrow(T))
or you can even remove them:
rownames(T) -
I assume that by table you mean data frame. Using the built in
data frame, BOD, try this:
ix - 2:4
BOD[ix, ]
Time demand
22 10.3
33 19.0
44 16.0
data.frame(BOD[ix, ], row.names = seq_along(ix))
Time demand
12 10.3
23 19.0
34 16.0
