I use gbm through the carriage without any problems, but when some variables were deleted from my data frame, it started to crash. I tried with versions of the named github and cran packages.
This is mistake:

There are no missing values, the answer is a 4th level coefficient, and the inputs are as follows:
Classes 'tbl_df', 'tbl' and 'data.frame': 1165 obs. of 14 variables: $ relatedness_cottle : num 0 0 8 8 0 6 0 6 6 0 ... $ dominance_cottle : int 4 6 0 6 6 6 6 4 4 4 ... $ time_spent : num 26832 20822 18893 13107 25406 ... $ num_color_changes : num 3.33 2.33 1.33 1 1 ... $ num_selects : num 1 0.667 2 0.667 1.667 ... $ show_select_match : num 1 0.667 0.333 1 1 ... $ default_size : num 0.667 0 0.667 0 0 ... $ select_order : Factor w/ 6 levels "future_past_present",..: 1 4 4 2 5 1 4 6 6 4 ... $ order_x : Factor w/ 6 levels "future_past_present",..: 4 4 4 4 4 3 4 4 4 4 ... $ color_past : Factor w/ 8 levels "black","blue",..: 5 1 6 8 5 7 1 6 6 5 ... $ color_present : Factor w/ 8 levels "black","blue",..: 1 4 4 4 6 8 4 4 1 4 ... $ color_future : Factor w/ 8 levels "black","blue",..: 2 2 2 2 2 2 1 2 8 2 ... $ dominance_cottle_future : int 0 4 0 4 2 0 4 2 2 0 ... $ relatedness_cottle_future: int 0 2 4 4 0 4 0 2 4 0 ...
But if I call gbm directly with the data framework, it works:
summary(gbm(clusterAssignment[trainIndex] ~ ., data = my_data[trainIndex,vars_for_clust])) Distribution not specified, assuming multinomial ... var rel.inf color_present color_present 33.533673 dominance_cottle dominance_cottle 33.170138 default_size default_size 25.321566 dominance_cottle_future dominance_cottle_future 5.674563 color_future color_future 2.300060 relatedness_cottle relatedness_cottle 0.000000 time_spent time_spent 0.000000 num_color_changes num_color_changes 0.000000 num_selects num_selects 0.000000 show_select_match show_select_match 0.000000 select_order select_order 0.000000 order_x order_x 0.000000 color_past color_past 0.000000 relatedness_cottle_future relatedness_cottle_future 0.000000
