Treemap / mosaic plot

mosaic plots:

assocplot (graphics)
Cohen-Friendly association plot indicating deviations from independence of rows and columns in a 2-dimensional contingency tables.

assocplot(x, col = c("black", "red"), space = 0.3,
main = NULL, xlab = NULL, ylab = NULL)

mosaicplot (graphics)
Plots a mosaic on the current graphics device.

mosaicplot(x, main = deparse(substitute(x)),
sub = NULL, xlab = NULL, ylab = NULL,
sort = NULL, off = NULL, dir = NULL,
color = NULL, shade = FALSE, margin = NULL,
cex.axis = 0.66, las = par("las"),
type = c("pearson", "deviance", "FT"), ...)

## S3 method for class 'formula':
mosaicplot(formula, data = NULL, ...,
main = deparse(substitute(data)), subset,
na.action = stats::na.omit)

mosaic (vcd)
Plots (extended) mosaic displays.

## Default S3 method:
mosaic(x, condvars = NULL,
split_vertical = NULL, direction = NULL, spacing = NULL,
spacing_args = list(), gp = NULL, expected = NULL, shade = NULL,
highlighting = NULL, highlighting_fill = grey.colors, highlighting_direction = NULL,
zero_size = 0.5, zero_split = FALSE, zero_shade = NULL,
zero_gp = gpar(col = 0), panel = NULL, main = NULL, sub = NULL, ...)

## S3 method for class 'formula'
mosaic(formula, data, highlighting = NULL,
..., main = NULL, sub = NULL, subset = NULL, na.action = NULL)

e.g. mosaic(Freq~Var3+Var2 | Var1, data=y, shade=T, zero_size=0, zero_shade=T, legend=T, labeling_args=list(set_varnames=c(Var1='Gruppe',Var2='aktiv', Var3='Gespräche'),set_labels=list(Var3=c('nein', 'ja'), Var1=c('WKG','IVG','keine')), rep=T))

An easy way to make a treemap

String operations in R

search and replace functions:
replace first occurrence:
- sub(pattern, replacement, x, ignore.case = FALSE)
and replace all occurences:
- gsub(pattern, replacement, x, ignore.case = FALSE)
e.g.
sub("ich", "wir", "ich Ich ICH") --------> "wir Ich ICH"
sub("ich", "wir", "ich Ich ICH", ignore.case=T) --------> "wir Ich ICH"
gsub("ich", "wir", "ich Ich ICH", ignore.case=T)--------> "wir wir wir"

Changing the order of Factors (in plots)

use reorder

-> Here is the example from the internal help:

bymedian <- with(InsectSprays, reorder(spray, count, median))

boxplot(count ~ bymedian, data = InsectSprays,
xlab = "Type of spray", ylab = "Insect count",
main = "InsectSprays data", varwidth = TRUE,
col = "lightgray")


reorder(spray,count,median) reorders the factor levels of InsectSprays$spray (the first argument of reorder), not the factor itself;


the third argument of reorder - some aggregate function - operates on the column InsectSprays$count (the second argument of reorder) and defines therefore the new order.


In the example above the median of InsectSprays$count for each group of InsectSprays$spray is calculated, and the levels are reordered ascending according to the medians of each group.


look at the differences:

> InsectSprays$spray
[1] A A A A A A A A A A A A B B B B B B B B B B B B C C C C C C C C C C C C D D
[39] D D D D D D D D D D E E E E E E E E E E E E F F F F F F F F F F F F
Levels: A B C D E F
> with(InsectSprays, reorder(spray,count,median))
[1] A A A A A A A A A A A A B B B B B B B B B B B B C C C C C C C C C C C C D D
[39] D D D D D D D D D D E E E E E E E E E E E E F F F F F F F F F F F F
attr(,"scores")
A B C D E F
14.0 16.5 1.5 5.0 3.0 15.0
Levels: C E D A F B
> with(InsectSprays, reorder(spray,count,min))
[1] A A A A A A A A A A A A B B B B B B B B B B B B C C C C C C C C C C C C D D
[39] D D D D D D D D D D E E E E E E E E E E E E F F F F F F F F F F F F
attr(,"scores")
A B C D E F
7 7 0 2 1 9
Levels: C E D A B F

you can also use it in the definition of graphics:
library(lattice)
picture<-barchart(reorder(name, Freq) ~ Freq | iv, groups=dropout, data=zahlen, xlab='', stack=T, auto.key=list(text=c('Aktiv','dropout'), columns=2))

If you want to change the order of a factor without an aggregating function (e.g. if the levels have a natural order like "tiny, normal, big") read the post

Trouble installing modules from CPAN

all the settings are done - and all should be ok - but it still does not work:

delete the folder .cpan from your home directory - and try again!

VBA-Error "Run-time error'-2147467259 (80004005)': Method 'Add of object 'CommandBar Controls' failed".

You have a faulting add-in. Go to Office Button>Excel Options...>Add-ins and
uncheck all then add one at a time back in and re-start excel when the issue
comes back,that's your issue.
