And explorations purposes I'm trying to plot a series of boxplots, all arranged in a single grid(4x3) by using variable COND as indipendent and the following ones:

"P3FCz"      
 [6] "P3Cz"        "P3Pz"        "LPPearlyFCz" "LPPearlyCz"  "LPPearlyPz" 
[11] "LPP1FCz"     "LPP1Cz"      "LPP1Pz"      "LPP2FCz"     "LPP2Cz"     
[16] "LPP2Pz"   

As indipendent variables. As I would to create the plot I described, I've been trying to modify the following code to plot the boxes one by one

for (i in 5:ncol(df_join)){
  print((ggplot(df_join, aes(x = COND, y = df_join[,i]))  
          geom_boxplot()  xlab("COND")   ylab(colnames(df_join)[i])))
  Sys.sleep(1)
}

As follows:

for (i in 5:ncol(df_join)){
  print(ggarrange(ggplot(df_join, aes(x = COND, y = df_join[,i]))  
          geom_boxplot()  xlab("COND")   ylab(colnames(df_join)[i]), ncol = 4, nrow = 3))
  Sys.sleep(1)

However, I'm keeping getting back just a series of overriden plots. How may I modify or to recode differently such lines to obtain the plot-grip(4X3) I'm interested in?

CodePudding user response:

Try pivoting and plotting with facets.

library(ggplot2)
ggplot(tidyr::pivot_longer(df_join, -c(ID, GR, SES, COND)), aes(COND, value))  
  geom_boxplot()  
  facet_wrap(~ name, nrow = 4, ncol = 3)

ggplot with facets
