colormapMiss {VIM} | R Documentation |
Colored map in which the proportion or amount of missing/imputed values in each region is coded according to a continuous or discrete color scheme. The sequential color palette may thereby be computed in the HCL or the RGB color space.
colormapMiss(x, region, map, imp_index = NULL, prop = TRUE, polysRegion = 1:length(x), range = NULL, n = NULL, col = c("red", "orange"), gamma = 2.2, fixup = TRUE, coords = NULL, numbers = TRUE, digits = 2, cex.numbers = 0.8, col.numbers = par("fg"), legend = TRUE, interactive = TRUE, ...) colormapMissLegend(xleft, ybottom, xright, ytop, cmap, n = 1000, horizontal = TRUE, digits = 2, cex.numbers = 0.8, col.numbers = par("fg"), ...)
x |
a numeric vector. |
region |
a vector or factor of the same length as |
map |
an object of any class that contains polygons and provides its own
plot method (e.g., |
imp_index |
a logical-vector indicating which values of ‘x’ have
been imputed. If given, it is used for highlighting and the colors are
adjusted according to the given colors for imputed variables (see |
prop |
a logical indicating whether the proportion of missing/imputed values should be used rather than the total amount. |
polysRegion |
a numeric vector specifying the region that each polygon belongs to. |
range |
a numeric vector of length two specifying the range (minimum and maximum) of the proportion or amount of missing/imputed values to be used for the color scheme. |
n |
for |
col |
the color range (start end end) to be used. RGB colors may be
specified as character strings or as objects of class
" |
gamma |
numeric; the display gamma value (see
|
fixup |
a logical indicating whether the colors should be corrected to
valid RGB values (see |
coords |
a matrix or |
numbers |
a logical indicating whether the corresponding proportions or numbers of missing/imputed values should be used as labels for the regions. |
digits |
the number of digits to be used in the labels (in case of proportions). |
cex.numbers |
the character expansion factor to be used for the labels. |
col.numbers |
the color to be used for the labels. |
legend |
a logical indicating whether a legend should be plotted. |
interactive |
a logical indicating whether more detailed information about missing/imputed values should be displayed interactively (see ‘Details’). |
xleft |
left x position of the legend. |
ybottom |
bottom y position of the legend. |
xright |
right x position of the legend. |
ytop |
top y position of the legend. |
cmap |
a list as returned by |
horizontal |
a logical indicating whether the legend should be drawn horizontally or vertically. |
... |
further arguments to be passed to |
The proportion or amount of missing/imputed values in x
of each region is
coded according to a continuous or discrete color scheme in the color range
defined by col
. In addition, the proportions or numbers can be shown
as labels in the regions.
If interactive
is TRUE
, clicking in a region displays more
detailed information about missing/imputed values on the R console. Clicking
outside the borders quits the interactive session.
colormapMiss
returns a list with the following components:
nmiss |
a numeric vector containing the number of missing/imputed values in each region. |
nobs |
a numeric vector containing the number of observations in each region. |
pmiss |
a numeric vector containing the proportion of missing values in each region. |
prop |
a logical indicating whether the proportion of missing/imputed values have been used rather than the total amount. |
range |
the range of the proportion or amount of missing/imputed values corresponding to the color range. |
n |
either a positive integer giving the number of equally spaced
cut-off points for a discretized color scheme, or |
start |
the start color of the color scheme. |
end |
the end color of the color scheme. |
space |
a character string giving the color space (either |
gamma |
numeric; the display gamma value (see
|
fixup |
a logical indicating whether the colors have been corrected to
valid RGB values (see |
Some of the argument names and positions have changed with versions 1.3 and
1.4 due to extended functionality and for more consistency with other plot
functions in VIM
. For back compatibility, the arguments
cex.text
and col.text
can still be supplied to ...
and
are handled correctly. Nevertheless, they are deprecated and no longer
documented. Use cex.numbers
and col.numbers
instead.
