Hi. I created a data.frame which compares the average and standard deviations of baby’s birth weights among smoking mothers and non-smoking mothers. Here is what I have:
Situation <- c("Smoke","NonSmoke") AverageWt <- c(meansmoke, meannonsmoke) StdWt <- c(sdsmoke,sdnonsmoke) d <- data.frame(Situation, AverageWt, StdWt, stringsAsFactors = FALSE)
And here is the result:
Situation AverageWt StdWt
1 Smoke 114.1095 18.09895
2 NonSmoke 123.0472 17.39869
Now what I'm trying to do is to use a plot to visualize the differences between them. Could anyone please help me? Thank you.
