The `fetch_cricinfo()` function will fetch data on all international cricket matches provided by ESPNCricinfo. Please respect the [ESPNCricinfo terms of use](https://www.espncricinfo.com/ci/content/site/company/terms_use.html) when using this function.

Here are some examples of its use.

```{r getdata, eval=FALSE, echo=FALSE}
# Avoid downloading the data when the package is checked by CRAN.
# This only needs to be run once to store the data locally
wt20 <- fetch_cricinfo("T20", "Women", "Bowling")
menODI <- fetch_cricinfo("ODI", "Men", "Batting", type = "innings", country = "Australia")
Indfielding <- fetch_cricinfo("Test", "Men", "Fielding", country = "India")
meg_lanning_id <- find_player_id("Meg Lanning")$ID
MegLanning <- fetch_player_data(meg_lanning_id, "ODI") %>%
  mutate(NotOut = (Dismissal == "not out")) %>%
  mutate(NotOut = tidyr::replace_na(NotOut, FALSE))

saveRDS(wt20, "inst/extdata/wt20.rds")
saveRDS(menODI, "inst/extdata/menODI.rds")
saveRDS(Indfielding, "inst/extdata/Indfielding.rds")
saveRDS(MegLanning, "inst/extdata/MegLanning.rds")
```

```{r loaddata, include=FALSE}
wt20 <- readRDS("../inst/extdata/wt20.rds")
menODI <- readRDS("../inst/extdata/menODI.rds")
Indfielding <- readRDS("../inst/extdata/Indfielding.rds")
MegLanning <- readRDS("../inst/extdata/MegLanning.rds")
```

## Women's T20 bowling data

```r
# Fetch all Women's T20 data
wt20 <- fetch_cricinfo("T20", "Women", "Bowling")
```

```{r woment20, message=FALSE, echo = FALSE}
wt20 %>%
  head() %>%
  knitr::kable(digits = 2)
```

```{r woment20graph, fig.width=10, fig.height=8}

  filter(Wickets > 20, !is.na(Country)) %>%
  ggplot(aes(y = StrikeRate, x = Country)) +
  geom_boxplot() +
  geom_point(alpha = 0.3, col = "blue") +
  ggtitle("Women T20: Strike Rates") +
  ylab("Balls per wicket") +
  coord_flip()
```

## Australian men's ODI data by innings

```r
# Fetch all Australian Men's ODI data by innings
menODI <- fetch_cricinfo("ODI", "Men", "Batting", type = "innings", country = "Australia")
```

```{r menodi, message=FALSE, echo=FALSE}

## Indian test fielding data

```r
Indfielding <- fetch_cricinfo("Test", "Men", "Fielding", country = "India")
```

```{r indiafielding, echo=FALSE}

  head() %>%

  ggplot(aes(x = Matches, y = Dismissals, col = wktkeeper)) +

```

## Meg Lanning's ODI batting

```r

MegLanning <- fetch_player_data(meg_lanning_id, "ODI") %>%
  mutate(NotOut = (Dismissal == "not out")) %>%

```

```{r meglanning, echo=FALSE}

  head() %>%
  knitr::kable()
```

```{r meglanninggraph}

MLave <- MegLanning %>%
  summarise(
    Innings = sum(!is.na(Runs)),
    Average = sum(Runs, na.rm = TRUE) / (Innings - sum(NotOut, na.rm=TRUE))
  ) %>%
  pull(Average)
names(MLave) <- paste("Average =", round(MLave, 2))
# Plot ODI scores
ggplot(MegLanning) +
  geom_hline(aes(yintercept = MLave), col = "gray") +
  geom_point(aes(x = Date, y = Runs, col = NotOut)) +
  ggtitle("Meg Lanning ODI Scores") +
  scale_y_continuous(sec.axis = sec_axis(~., breaks = MLave))
```
