What is Mosaic in R?
The mosaic package is designed to facilitate the use of R in statistics and calculus instruction by providing a number of functions that (a) make many common tasks fit into a common template, and (b) simplify some tasks that would otherwise be too complicated for beginners.
What mosaic plot tells us?
A mosaic plot is a graphical display that allows you to examine the relationship among two or more categorical variables. Then each bar is split vertically into bars that are proportional to the conditional probabilities of the second categorical variable.
How do you tell if a mosaic plot is independent or dependent?
It is usually easy to tell from a mosaic plot whether the two variables are independent. When they are independent, all proportions are the same and so the boxes line up in a grid.
How many variables are in a mosaic plot?
two variables
Mosaic plots show relationships For two variables, the width of the columns is proportional to the number of observations in each level of the variable plotted on the horizontal axis.
How do I get mosaic in R?
Go to the Packages tab in the lower right portion of the RStudio console and click on Install Packages. 5. Make sure you’re still connected to the internet and install from the Repository both the mosaic and openintro packages by typing “mosaic, openintro” in the textbox. Then click Install.
How do you make a mosaic plot in R?
R Mosaic Plot Syntax
- data: Please specify the DataFrame or List that contains the data to draw a mosaic plot.
- subset: You can restrict the Mosaic plot to draw some data by specifying the vector of values.
- x: Please specify the data from which you want to draw the mosaic plot.
- sort: Ordering the vector variables.
What is a Spineplot?
A spine plot is a specific type of mosaic plot for only two variables. It is similar to the compound bar chart, but now the width of the bar is set by the proportion of each horizontal category.
Why is it called a Marimekko chart?
We’ll call it Marimekko because that’s a common name in the Tableau world, though mosaic plot is the more widely-used name. I suspect that the reason Tableau users have wanted this chart since 2009 is that it combines multiple variables of data into a single rectangle of a plot.
What is Chi square plot?
A chi-squared Q-Q plot is one useful way informally to assess whether d2 is distributed as. χp. 2. It is similar to a normal scores plot that is often used to assess univariate normality.
What is Mosaic or Mekko charts?
A mosaic plot (also known as a Marimekko diagram) is a graphical method for visualizing data from two or more qualitative variables. Mosaic plots are also called Mekko charts due to their resemblance to a Marimekko chart.
What is strip plot?
A strip plot is a graphical data anlysis technique for summarizing a univariate data set. The strip plot is an alternative to a histogram or a density plot. It is typically used for small data sets (histograms and density plots are typically preferred for larger data sets).
How do I install an Openintro package in R?

What does 45, x / 46, XY mosaicism mean?
45,X/46,XY mosaicism. 45,X/46,XY mosaicism, also known as X0/XY mosaicism and mixed gonadal dysgenesis, is a rare disorder of sex development in humans associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. This is called a mosaic karyotype because, like tiles in mosaic floors or walls, there is more than one type of cell.
Which is the formula for a mosaic plot?
Mosaic Plots. For extended mosaic plots, use mosaic(x, condvar=, data=) where x is a table or formula, condvar= is an optional conditioning variable, and data= specifies a data frame or a table. Include shade=TRUE to color the figure, and legend=TRUE to display a legend for the Pearson residuals.
Which is the most common phenotypical expression of 45, x / 46 mosaicism?
The phenotypical expression may be ambiguous, male or female depending on the extent of the mosaicism. The most common presentation of 45,X/46,XY karyotype is phenotypically normal male, next being genital ambiguity.
Is there a cure for 45, x / 46, XY?
When diagnosis of 45,X/46,XY is made postnatally, it is generally because of an abnormal phenotype; however, rare normal males have been identified. The most common presentation is TS, and both females and males with a 45,X/46,XY karyotype show poor growth and seem to benefit from GH treatment to achieve a normal growth pattern (144).
