Object 'myvariable' not found.But my variable exists if i run str(dataframe)












-5















I have the Mroz dataframe and i am trying to get the median of the inc variable of people that are assigned as "no" and later as "yes" in the wc variable. But it says that the object wc does not exist although when i run str(Mroz) it is written along with all the other variables.



str(Mroz)



mean(Mroz$inc[wc=="No"])



mean(Mroz$inc[wc=="Yes"])





r

  • Try mean(Mroz$inc[Mroz$wc=="No"]) for mean or median(Mroz$inc[Mroz$wc=="No"]) to get median

  • Use na.rm argument, mean(Mroz$inc[Mroz$wc=="No"], na.rm = TRUE) and same for median

  • It still says NaN

  • The wc variable take only yes or no so how can it be a number(cause from what i have seen nan stands for not a number)

Your requirement: Need mean/median value of "inc" variable by the field in "wc" Column



For the above requirement, you can use below code



library(dplyr)

Mroz %>% group_by(wc) %>% summarise(mean(inc))

  • Thank you very much it worked!Now i want to make a boxplot but when i write boxplot(Mroz$inc~wc,main="Income by age", it says object wc not found.It is the same problem again so what should i do now?(The variable wc is defined if i use the str command so i dont know what is it saying it is not found)

1 I tried to upgrade a yummy sandwich made of two test slices (@JsonTest and @JdbcTest in my case, crunchy test code in between) adding spring boot 2.1 flavour to it. But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
