Good day,
The example below fails on Windows with Error in grid.Call.graphics(C_text,
as.graphicsAnnot(x$label), x$x, x$y: Metric information not available for this
family/device.
library(ggplot2)
aPlot <- ggplot(ToothGrowth, aes(x = factor(dose), y = len)) + geom_boxplot() +
ggtitle("Test", subtitle = ggplot2::expr(paste("p", " = ", "6.23", " ×
", "10"^"-5")))
svg("test.svg"); aPlot; dev.off();
but there is no such problem on a Debian Linux server. The plot in Windows
appears fine in an R graphics window. The error only occurs when exported as an
SVG file. Using %*% instead of × avoids the error but it's perhaps worth
mentioning in case it could be easily handled by R.
