Dear all I seek some help how to remove unused facets in ggplot
Here is my code p <- ggplot(met, aes(x=datum, y=lsp)) p+geom_point(size=5)+geom_line()+facet_grid(.~vzorek) As you can see, there are some empty facets. Is there any reasonably simple way how to automatically get rid of empty facets and adjust width of remaining facets? I could programmatically remove empty levels of vzorek before invoking ggplot but before are start with such approach I would like to check if there is some solution within ggplot. Here are some toy data. met <- structure(list(datum = structure(c(18282, 18282, 18282, 18290, 18290, 18290, 18296, 18296, 18296, 18304, 18304, 18304, 18311, 18311, 18311, 18317, 18317, 18317, 18317, 18324, 18324, 18324, 18332, 18332, 18332, 18340, 18340, 18340, 18345, 18345, 18345, 18352, 18352, 18369, 18369, 18369, 18375, 18375, 18375), class = "Date"), vzorek = structure(c(9L, 8L, 2L, 5L, 9L, 6L, 1L, 7L, 8L, 9L, 5L, 1L, 2L, 7L, 8L, 5L, 2L, 1L, 7L, 9L, 7L, 5L, 4L, 2L, 1L, 3L, 8L, 5L, 9L, 2L, 1L, 7L, 8L, 9L, 8L, 2L, 1L, 7L, 5L ), .Label = c("a", "b", "c", "d", "e", "f", "g", "h", "i" ), class = "factor"), lsp = c(55.3, 54.68, 53.15, 54.55, 55.17, NA, NA, NA, 54.79, 55.27, 54.44, NA, 53.31, NA, 54.52, 54.35, 53.88, NA, NA, 55.21, NA, 54.39, NA, 52.95, NA, NA, 54.56, 54.39, 55, 53.2, NA, NA, 54.54, NA, 54.57, 53.31, NA, NA, NA), asp = c(-1.63, -1.47, -1.19, -1.35, -1.62, NA, NA, NA, -1.46, -1.65, -1.4, NA, -1.2, NA, -1.5, -1.36, -1.21, NA, NA, -1.64, NA, -1.36, NA, -1.21, NA, NA, -1.5, -1.42, -1.68, -1.2, NA, NA, -1.47, NA, -1.47, -1.22, NA, NA, NA), bsp = c(-7.19, -5.65, -7.22, -5.31, -7.12, NA, NA, NA, -5.65, -7.14, -5.34, NA, -7.16, NA, -5.68, -5.3, -7.14, NA, NA, -7.14, NA, -5.34, NA, -7.17, NA, NA, -5.65, -5.34, -7.25, -7.19, NA, NA, -5.65, NA, -5.66, -7.14, NA, NA, NA)), row.names = c(NA, -39L), class = "data.frame") > Cheers Petr
