# CitationMetricsData 




The goal of CitationMetricsData is to provide easy access to career-long and single-year citation data for top-cited scientists, based on the dataset 'August 2024 data-update for "Updated science-wide author databases of standardized citation indicators"' by Ioannidis, John P.A

## Installation

You can install the development version of CitationMetricsData from [GitHub](https://github.com/) with:

``` r
# install.packages("devtools")
devtools::install_github("thiyangt/CitationMetricsData")
```

```{r}
library(CitationMetricsData)
```

## Career-long data are updated to end-of-2023

```{r}
head(career.long.data)
```

##  Single recent year data pertain to citations received during calendar year 2023

```{r}
head(single.year.data)
```

# Data Visualisations 

```{r, warning=FALSE, message=FALSE, echo=FALSE}
library(tidyverse)
library(countrycode)
career.long.data$country.name <- countrycode(career.long.data$cntry, origin = 'iso3c', destination = 'country.name')
top_20_cntry <- career.long.data %>%
  count(country.name) %>%
  arrange(desc(n)) %>%
  head(20)

# Plot the bar chart
ggplot(top_20_cntry, aes(x = reorder(country.name, n), y = n)) +
  geom_bar(stat = "identity", fill = "#1b9e77") +
  coord_flip() +  # Flip coordinates to make it horizontal
  labs(title = "Top 20 Countries by Number of Top-Cited Researchers",
  subtitle= "(Based on Career-long Data)",
       x = "Country",
       y = "Number of Researchers") +
  theme_minimal()
```

```{r, echo=FALSE, warning=FALSE}
single.year.data$country.name <- countrycode(single.year.data$cntry, origin = 'iso3c', destination = 'country.name')
top_20_cntrys <- single.year.data |>
  count(country.name) |>
  arrange(desc(n)) |>
  head(20)

# Plot the bar chart
ggplot(top_20_cntrys, aes(x = reorder(country.name, n), y = n)) +
  geom_bar(stat = "identity", fill = "#d95f02") +
  coord_flip() +  # Flip coordinates to make it horizontal
  labs(title = "Top 20 Countries by Number of Top-Cited Researchers ",
       subtitle = "(Based on Single-year Data)",
       x = "Country",
       y = "Number of Researchers") +
  theme_minimal()
