Remove or hide zeroline on R ggplot2/factoextra plots

correspondence-analysis, factoextra, ggplot2, pca, r

Solution

The only way I have found so far is to add the option

axes.linetype=NA

You'll get the plot without the lines. However this makes a warning message show up saying that there can be missing values, but the plot seems ok.

The lines you are trying to get rid off are geom_hline and geom_vline added by the function:

.fviz_finish(p, X, axes, axes.linetype, ...)

called at some point by the one you are using.

I have use the following code and data to produce the example:

library(ggplot2)
library(factoextra)
library(FactoMineR)

res.ca<-CA(housetasks,graph = FALSE)
fviz_ca_biplot(res.ca,axes.linetype=NA)

fviz_ca_biplot(res.ca,axes.linetype=NA)

## Warning: Removed 1 rows containing missing values (geom_segment).
## Warning: Removed 1 rows containing missing values (geom_segment).
## Warning: Removed 1 rows containing missing values (geom_segment).
## Warning: Removed 1 rows containing missing values (geom_segment).

Following the options of your example:

fviz_ca_biplot(res.ca,
               geom =c( "text", "point"),
               col.col = "#FF6600",
               col.row = "#336699",
               MAP = "symbiplot",
               labelsize = 5,
               repel = TRUE,
               title = " ",
               axes.linetype=NA
) +
  theme(axis.line=element_blank(),
        axis.text.x=element_blank(),
        axis.text.y=element_blank(),
        axis.ticks=element_blank(),
        axis.title.x=element_blank(),
        axis.title.y=element_blank(),
        legend.position="none",
        panel.background=element_blank(),
        panel.border=element_blank(),
        panel.grid.major=element_blank(),
        panel.grid.minor=element_blank(),
        plot.background=element_blank())

Hope it helps you!

Problem

I am using this factoextra package in R to do Correspondent Analysis. When I print out the result plot, I can't find the option to hide the x and y zeroline. I know that the theme setting is based on ggplot2. Can anyone help me to figure out how to hide those two lines? Please find the code below. ``` fviz_ca_biplot(gen_show_ns.ca, geom =c( "text", "point"), col.col = "#FF6600", col.row = "#336699", MAP = "symbiplot", labelsize = 5, repel = TRUE, title = " " ) + theme(axis.line=element_blank(), axis.text.x=element_blank(), axis.text.y=element_blank(), axis.ticks=element_blank(), axis.title.x=element_blank(), axis.title.y=element_blank(), legend.position="none", panel.background=element_blank(), panel.border=element_blank(), panel.grid.major=element_blank(), panel.grid.minor=element_blank(), plot.background=element_blank())}) ``` Other reference link please see here: ggplot2 theme Any suggestion helps! Thanks so much
