Creating a jobs time-lime for resume in R
- 4 minsLet’s say we define a data.frame with the jobs I’ve got from 2008 to 2017:
jobs <- data.frame(
employer = c( "GICO", "TES", "UAB", "IFAE", "ISGlobal" ),
year_start = as.Date( c( "2008-07-01", "2009-11-01", "2010-09-01", "2011-07-01", "2013-09-01" ) ),
year_end = as.Date( c( "2009-10-31", "2010-07-31", "2011-06-30", "2012-09-30", "2017-08-31" ) ),
id = 1,
stringsAsFactors = FALSE
)
The content of the data.frame is easy understandable:
- The
employershows the nanme of the compaty/institution who employed me. - The
year_startindicates the date when I started to work for a given emplyer. - The
year_endindicates the date when I stoped working for a given emplyer.
The dificult to understand is the id. It indicates the track where the employer whill be shown. I want to see all employers in the same track, so id has the same value for all of the entries in the data.frame.
Then we start working with ggplot:
library(ggplot2)
We will take advantage of the geom_segment to create the time line:
p <- ggplot( jobs, aes( colour = employer) ) +
geom_segment(
aes( x = year_start, xend = year_end, y = employer, yend = employer ), size = 7
)
p
Next step sit to glat the segments to a single line. To this end we use the id:
p <- ggplot( jobs, aes( colour = employer) ) +
geom_segment(
aes( x = year_start, xend = year_end, y = id, yend = id ), size = 7
)
p
Now, we clean the environemnt to get a clear view of the time line.
p <- p + theme_minimal() + xlab( "" ) + ylab( "" ) +
theme(
legend.position = "top",
axis.text.x = element_text(angle = 90, hjust = 1),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank()
)
p
Optionally we can update the colors:
pal <- colorRampPalette(c("LightCyan", "DarkCyan"))
colors <- pal(length(unique(jobs$employer)))
names(colors) <- unique(jobs$employer)
p + scale_colour_manual(values=colors)
