ggplot2 - Store static ggplot to variable as value in R -


i'm creating multiple ggplots in loop, storing them in list. problem "data" parameter pass ggplot changing on each iteration, , therefore when later print plots, printed last revision of "data" dataframe.

what do, save ggplot statically variable (by value) in way not reevaluate "data" uppon printing. ideas?

for example, if each every ggplot in list, use last revision of 'scalebounds' (from last iteration) 'data' of ggplot.

my code:

scaleplotlist <- list() (i in 1:number_of_scales)   {     plot.new()     row <- df[i,]      min <- row$min     max <- row$max     <- max(min(row$your_business,max),min)     pinseq <- seq(from=min,to=max,length.out=6)      scalebounds <-data.frame(x=c(pinseq[1],pinseq[2],pinseq[2],pinseq[1],pinseq[2],pinseq[3],pinseq[3],pinseq[2],pinseq[3],pinseq[4],pinseq[4], pinseq[3],pinseq[4],pinseq[5],pinseq[5],pinseq[4],pinseq[5], pinseq[6], pinseq[6], pinseq[5]),                             y=c( 0,0,1,1, 0,0,1,1, 0,0,1,1, 0,0,1,1, 0,0,1,1 ),                             t=c( 1,1,1,1, 2,2,2,2, 3,3,3,3, 4,4,4,4, 5,5,5,5 ))      currentplot <- ggplot() +        geom_polygon(data=scalebounds, mapping=aes(x=x,y=y,group=t,fill=-t)) +        scale_colour_brewer() +       labs(x="",y="") +       ylim(0,1.5) +       geom_segment(aes(x=you,y=0,xend=you,yend=1.2), colour="#3d3d3d", size=3, lineend = "round") +       geom_text(label="min", aes(x=pinseq[1], y=0), size=5, colour="#fcfcfc", fontface="bold", hjust=-0.1, vjust=-.7) +        geom_text(label="max", aes(x=pinseq[6], y=0), size=5, colour="#fafafa", fontface="bold", hjust=1.1, vjust=-.7) +       geom_text(label="you", aes(x=you, y=.5), size=8, colour="#fafafa", fontface="bold", hjust=-0.1) +       theme_nothing()        scaleplotlist[[length(scaleplotlist)+1]] <- currentplot      }

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
