Hi all, I have a dataframe called 'table' in which both factors and numerical values are stored. > dim(table) [1] 990 6 The fist 10 lines of table, to get an idea: > table[1:10,] QueryNo Query type Ret Prec Rec 1 1 Sports exact 1 1 0.01 2 5 Office exact 0 NaN 0.00 3 6 Meeting exact 0 NaN 0.00 4 7 Studio exact 0 NaN 0.00 5 9 Building exact 0 NaN 0.00 6 10 Desert exact 1 1 0.01 7 12 Mountain exact 0 NaN 0.00 8 13 Road exact 0 NaN 0.00 9 14 Sky exact 0 NaN 0.00 10 15 Snow exact 0 NaN 0.00 I want to plot column 5 (numerical values) against column 3 (factors). plot(table[,c(3,5)]) works fine. However, I don't want to include all 30 levels of the factor in the plot. I would like a plot of just 5 factors: "exact", "broader1", "narrower4", etc. Could anyone tell me how to do this, or where to find information about this? Thanks! Laura

[R] Plot only a subset of all factors in dataframe
Try this:
plot(subset(df[,c(3,5)], type %in% c("exact", "broader1",
"narrower4")))

[R] Plot only a subset of all factors in dataframe
?subset The select argument allows to select the columns and the subset argument the rows. domenico Laura Hollink wrote:> Hi all, > I have a dataframe called 'table' in which both factors and numerical > values are stored. > > > dim(table) > [1] 990 6 > > The fist 10 lines of table, to get an idea: > > > table[1:10,] > QueryNo Query type Ret Prec Rec > 1 1 Sports exact 1 1 0.01 > 2 5 Office exact 0 NaN 0.00 > 3 6 Meeting exact 0 NaN 0.00 > 4 7 Studio exact 0 NaN 0.00 > 5 9 Building exact 0 NaN 0.00 > 6 10 Desert exact 1 1 0.01 > 7 12 Mountain exact 0 NaN 0.00 > 8 13 Road exact 0 NaN 0.00 > 9 14 Sky exact 0 NaN 0.00 > 10 15 Snow exact 0 NaN 0.00 > > I want to plot column 5 (numerical values) against column 3 (factors). > > plot(table[,c(3,5)]) works fine. > > However, I don't want to include all 30 levels of the factor in the > plot.
