[r] Removing display of row names from data frame

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.

Recently I had the same problem when using htmlTable() (‘htmlTable’ package) and I found a simpler solution: convert the data frame to a matrix with as.matrix():

htmlTable(as.matrix(df))

And be sure that the rownames are just indices. as.matrix() conservs the same columnames. That's it.

UPDATE

Following the comment of @DMR, I did't notice that htmlTable() has the parameter rnames = FALSE for cases like this. So a better answer would be:

htmlTable(df, rnames = FALSE)

If you want to format your table via kable, you can use row.names = F

kable(df, row.names = F)

My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.

I find datatable in library DT robust to handle rownames, and columnames

Library DT
datatable(df, rownames = FALSE)  # no row names 

refer to https://rstudio.github.io/DT/ for usage scenarios

Yes I know it is over half a year later and a tad late, BUT

row.names(df) <- NULL

does work. For me at least :-)

And if you have important information in row.names like dates for example, what I do is just :

df$Dates <- as.Date(row.names(df))

This will add a new column on the end but if you want it at the beginning of your data frame

df <- df[,c(7,1,2,3,4,5,6,...)]

Hope this helps those from Google :)
