Is there an equivalent in ggplot2 to plot this dataset? I use matplot, and read that qplot could be used, but it really does not work. ggplot/matplot

```
data<-rbind(c(6,16,25), c(1,4,7), c(NA, 1,2), c(NA, NA, 1))
as.data.frame(data)
matplot(data, log="y",type='b', pch=1)
```

Answer:

You can create a similar plot in ggplot, but you will need to do some reshaping of the data first.

```
library(reshape2)
#ggplot needs a dataframe
data <- as.data.frame(data)
#id variable for position in matrix
data$id <- 1:nrow(data)
#reshape to long format
plot_data <- melt(data,id.var="id")
#plot
ggplot(plot_data, aes(x=id,y=value,group=variable,colour=variable)) +
geom_point()+
geom_line(aes(lty=variable)) +
scale_y_log10(breaks=c(1,2,5,10,25))
```

My output:
