## What skills and qualifications are required for data science related jobs?



The DSjobtraker package compiles data from 1172 job advertisements in data science and statistics, making it an invaluable tool for learning key skills required in these areas. Here is a word cloud of 97 requested skills mentioned in the job advertisements. It provides insights into the most sought-after skills in the field.


```{r, echo=FALSE, warning=FALSE, message=FALSE}
library(ggwordcloud)
library(DSjobtracker)

word <- colnames(DStidy[, 7:94])
word <- gsub("_", " ", word)
frequency <- colSums(DStidy[, 7:94], na.rm=TRUE)
df <- data.frame(word = word,
                 freq = frequency)

ggplot(data = df,
       aes(label = word, size = freq, col = as.character(freq))) +
  geom_text_wordcloud(rm_outside = TRUE, max_steps = 1,
                      grid_size = 1, eccentricity = .9)+
  scale_size_area(max_size = 20)+
 # scale_color_brewer(palette = "Paired", direction = -1)+
  theme_void()

```
