Frequency Tables of selected variables
library(plyr)
# Frequency table for variable 'H2GI1M'
count(data1, 'H2GI1M')
## H2GI1M freq
## 1 1 368
## 2 2 356
## 3 3 409

## 13 NA 1667
In the freq. table clearly we can observe that there is almost equal distribution of the
data over 12 values of variable and there are 1667 missing cases (NAs).

In the freq. table above, clearly, we can observe that the freq. distribution varied from as
low as 1 to as high as 624 and there are no missing cases.
# Frequency table for variable 'IMONTH'
count(data1, 'IMONTH')
## IMONTH freq
## 1 1 3
## 2 4 92
## 3 5 1593
## 4 6 1810
## 5 7 1300
## 6 8 1102
## 7 9 438
## 8 10 117
## 9 11 31
## 10 12 18
Finally, we can see In the freq. table above that May through August months has highest frequency of occurnaces and there are no missing cases in the data.
