I am creating a dataframe using this code:
df <- data.frame(dbGetQuery(con, paste('select * from test')))
Which results in this:
UID BuildingCode AccessTime
1 123456 BUILD-1 2014-06-16 07:00:00
2 364952 BUILD-2 2014-06-15 08:00:00
3 95865 BUILD-1 2014-06-06 09:50:00
I am then trying to remove the row names (1, 2, 3, etc) as suggested here by using this code:
rownames(df) <- NULL
But then when I print out df
it still displays the row names. Is there a way to not include the row names when creating the data frame? I found a suggestion about row.name = FALSE
but when I tried it I just got errors (I might have placed it in the wrong place).
EDIT: What I want to do is convert the dateframe to a HTML table and I don't want the row name to be present in the table.
You have successfully removed the row names. The print.data.frame
method just shows the row numbers if no row names are present.
df1 <- data.frame(values = rnorm(3), group = letters[1:3],
row.names = paste0("RowName", 1:3))
print(df1)
# values group
#RowName1 -1.469809 a
#RowName2 -1.164943 b
#RowName3 0.899430 c
rownames(df1) <- NULL
print(df1)
# values group
#1 -1.469809 a
#2 -1.164943 b
#3 0.899430 c
You can suppress printing the row names and numbers in print.data.frame
with the argument row.names
as FALSE
.
print(df1, row.names = FALSE)
# values group
# -1.4345829 d
# 0.2182768 e
# -0.2855440 f
Edit: As written in the comments, you want to convert this to HTML. From the xtable
and print.xtable
documentation, you can see that the argument include.rownames
will do the trick.
library("xtable")
print(xtable(df1), type="html", include.rownames = FALSE)
#<!-- html table generated in R 3.1.0 by xtable 1.7-3 package -->
