diag = FALSE,
reorder = TRUE,
signif = c("stars", "pval"),
show = c("all", "signif"),
p_val = 0.05,
caption = TRUE,
digits.cor = 2,
digits.pval = 3,
col.low = "red",
col.mid = "white",
col.high = "blue",
lab.x.position = NULL,
lab.y.position = NULL,
legend.position = NULL,
legend.title = "Pearson's\nCorrelation",
size.text.cor = 3,
size.text.signif = 3,
size.text.lab = 10,
...
)
Arguments
- x
The data set.
- type
The type of heat map to produce. Either
lower
(default) to produce a lower triangle heat map orupper
to produce an upper triangular heat map.- diag
Plot diagonal elements? Defaults to
FALSE
.- reorder
Reorder the correlation matrix to identify the hidden pattern? Defaults to
TRUE
.- signif
How to show significant correlations. If
"stars"
is used (default), stars are used showing the significance at 0.05 (""), 0.01 ("") and 0.001 ("") probability error. Ifsignif = "pval"
, then the p-values are shown.- show
The correlations to show. Either
all
(default) orsignif
(only significant correlations).- p_val
The p-value to the correlation significance.
- caption
Logical. If
TRUE
(Default) includes a caption with the significance meaning for stars.- digits.cor, digits.pval
The significant digits to show for correlations and p-values, respectively.
- col.low, col.mid, col.high
The color for the low (-1), mid(0) and high (1) points in the color key. Defaults to
blue
,white
, andred
, respectively.- lab.x.position, lab.y.position
The position of the x and y axis label. Defaults to
"bottom"
and"right"
iftype = "lower"
or"top"
and"left"
iftype = "upper"
.- legend.position
The legend position in the plot.
- legend.title
The title of the color key. Defaults to
"Pearson's Correlation"
.- size.text.cor
The size of the text for correlation values. Defaults to 3.
- size.text.signif
The size of the text for significance values (stars or p-values). Defaults to 3.
- size.text.lab
The size of the text for labels. Defaults to 10.
