Custom values on axes in lattice

[leszi]

Hi all,

is there an option to manually change values on axes in a lattice plot without changing data input?
Somehow my time series values (1998:2009) on a barchart changed into (1:12).

TIA

Here is a simple example of making a barchart with {lattice}, changing the default orientation, and (one way) of forcing the x-axis tick labels to be the "years" you want.

library(lattice)
my_df <- data.frame(year=c(1998:2009), 
                    sales=c(12,13,15,13,10,8,11,13,19,25,11,14))
my_df
#>    year sales
#> 1  1998    12
#> 2  1999    13
#> 3  2000    15
#> 4  2001    13
#> 5  2002    10
#> 6  2003     8
#> 7  2004    11
#> 8  2005    13
#> 9  2006    19
#> 10 2007    25
#> 11 2008    11
#> 12 2009    14
barchart(sales~year, data=my_df)

barchart(sales~year, data=my_df, horizontal=FALSE)

barchart(sales~as.character(year), data=my_df, horizontal=FALSE)
