Summary with graph
Summary of data frame in a convenient table. Summary of a variable with statistics and graph
summ(x, ...)
## Default S3 method:
summ(x, by=NULL, graph = TRUE, box = FALSE, pch = 18,
ylab = "auto", main = "auto", cex.X.axis = 1, cex.Y.axis = 1,
dot.col = "auto", ...)
## S3 method for class 'factor'
summ(x, by=NULL, graph=TRUE, ...)
## S3 method for class 'logical'
summ(x, by=NULL, graph=TRUE, ...)
## S3 method for class 'data.frame'
summ(x, ...)x |
'x' can be a data frame or a vector |
by |
a stratification variable, valid only when x is a vector |
graph |
automatic plot (sorted dot chart) if 'x' is a vector |
box |
add a boxplot to the graph (by=NULL) |
pch |
plot characters |
ylab |
annotation on Y axis |
main |
main title of the graph |
cex.X.axis |
character extension scale of X axis |
cex.Y.axis |
character extension scale of Y axis |
dot.col |
colour(s) of plot character(s) |
... |
additional graph parameters |
For data frames, 'summ' gives basic statistics of each variable in the data frame. The other arguments are ignored.
For single vectors, a sorted dot chart is also provided, if graph=TRUE (default).
