DATA FRAME (Creation & Accessing Elements) IN R - PROGRAMMING || DATA STRUCTURES IN R

DATA FRAME CREATION using data.frame() function syntax: data.frame(col_name1=c(val1,val2,. . ), col_name2=c(val1,val2, . . ), . . . . . . ) or col_name1=c(val1,val2, . . . ) col_name2=c(val1,val2, . . . ) data.frame(col_name1,col_name2) ACCESSING DATAFRAME dataframe_name[index] - return columns with specified index dataframe_name[c(col1,col2,...)] - return multiple columns having given index dataframe_name[["col_name']] - return column having given name dataframe_name$col_name - return column having given name dataframe_name$col_name[index] - return element having index in specified column ---------------------------------------------------------------------------------------------------------------- R PROGRAMMING https://studio.youtube.com/playlist/P...
